    Further to my recent threads about using the EPS from a Prius in my project car, I'm now trying to work out what other steering wheels will fit the column.

    Several companies advertise Prius steering wheel hubs, but these are for cars fitted with airbags - which mine isn't, so I need an alternative that has the correct spline but no airbag.

    The actual wheel I intend to use is a Momo with 6 bolts on a 70mm PCD, and this fitment seems to be common on a lot of the hubs used on Toyotas too. But I don't know which model to ask for!

    I don't think any of that stuff matters If you look at Grant just to look at how it's done how they do it they have a little spline adapter that screws to the back of the steering wheel that has your horn contact on it which you wouldn't be using you would use the hub adapter and that would adapt about 30 or 40 different steering wheels to fit your business The Toyota's very popular I don't remember how many splines I'll try and count them tonight for you but my Corolla steering wheel will fit the Prius which will even fit on a truck up to a certain point The airbag business doesn't matter You could use an airbag steering wheel and the airbag wouldn't be hooked up to anything and if you could make the sidewing buttons work anything you could also use the steering or the turn signal assembly and the clock spring but then you're getting things very complicated for probably not a very complicated car but I have a couple of the grant steering wheel hub adapter sitting in my toolbox It's a very cheap aluminum design that matches the Toyota pretty standard steering wheel hub that I know from 74 to late up in the '90s and mid-2000s is pretty much the same for some reason 19 splines or something like that comes to mind I know it's a 19 mm nut. But you won't have any problem with this. So if you use the Toyota steering box assembly that's above your knees it'll have the shaft already sticking out of it and you'll be able to pick from a plethora of wheels whether you want to stock Toyota wheel and aftermarket Grant I'm working on fitting an Emerson fittipaldi E3 wheel personally

    Thank you for taking the time to answer! Over here in the UK we don't have Grant as an option - it's useful to know that a Corolla wheel will fit though.

    You have companies that make steering wheels I'm pretty sure If I have to call my buddies on Toyota mods blazella and all of those guys on the net from New Zealand and all that they will give me the proper name for your product I'm actually quite surprised Grant doesn't sell in your country because I've seen them on vehicles in your country that have been handmade by people that can do that The guy I mentioned above probably doesn't exist anymore as he's older than I am He used to fly car parts all over the country to build his race car in New Zealand He was a flyboy He flew planes all over the world and would pick up car parts when he was in places where he needed to pick them up America Germany Spain wherever I'm serious it just logs of this online but I'm sure no one's really interested I'll try and take a picture of the adapter plate that adapts Grant and probably other steering wheels from just the raw steering wheel with the five holes in the middle or whatever it is to the splind shaft of the Toyota I have it sitting in my toolbox You could also have something like this made up very easily by even a poor machine shop that's aluminum casting like thing. If you look at Emerson fittipaldi steering wheels You will see what the adapters look like to fit Ferraris and Lamborghinis and Mercedes and well they're very similar for the Toyota there was a thing called the Supra which was a supercar at one point in the world that people were doing all kinds of work to that JZ engine and interior. But yes you will find from somewhere around 1970 all the way up to probably 1997 or better The center steering wheel spleen on almost all Toyota cars and even some of the trucks are the same I've taken steering wheels out of my '85 silica and dropped and right on but 2007 Prius other than applying the nut it's on there now your buttons and all that are another story like I said before. But we're not really working with the buttons and accessories at this point we're just talking about what steering wheels can go where basically so you should have thousands to choose from in salvage yards and here online from people I buy steering wheels for 2008 Prius in like new perfect condition I mean they look Brent when I receive them from the seller in Richmond Virginia they look brand new It's ridiculous 50 bucks and you know what they look like when they're crap

    I ordered a boss for a Corolla last night - I'll have to wait until it arrives before I can see if it fits though!

    I'm not sure I know what a boss is but anyway I don't know if you've ordered a steering wheel or you've been able to get the center section of the steering wheel I didn't think that was removable The hub of the steering wheel with the spleen shaft hole in the center of it I don't think that comes off my Corolla or my Prius steering wheel I have one sitting here I'll look at it again so somehow you've ordered the spleened hold metal piece I guess that could be called the boss that's going to drop on your whatever your building The steering shaft of the assembly you're using Yes it should drop right on there in the 19 mm bolt should apply without problem and hold the steering wheel in place.

    Have you ever been on a list called the Toyota mods list The Toyota modifications list server? There are a bunch of guys from the UK on Toyota mods that do just what you're doing here I don't know what you're building a race car or a Chapman vehicle or whatever it is open wheel roadster The guys on that list in the UK are constantly building these Chatham roadsters and all of this kind of stuff from scratch.

    Toymods? Yes, I have been on there (I think it's an Aussie site), but I'll go and look again; my project car is a classic 70's Italian chassis into which I'm dropping a very large, very modern, and very powerful powerplant!

    Regarding what a 'boss' is - it's what we on this side of the pond call the piece that sits on the end of the steering column, and to which the steering wheel fits.

    Toyota mods list server I'm not sure who founded that but the Australian presents has been heavy since it's inception It came on when AOL went online and everything was black and green screen there were no pictures no voice none of that strictly a keyboard. But all of the guys on there were building well those Chatham type of things open wheel roadsters Morgan plus eight copies all kinds of crazy stuff putting Toyota engines and some of those things hence why they're on toy mods But anyway yeah this has been going on since like oh I don't know 87 89 somewhere in there I've been a member over there gosh I should go look at my stuff I rarely even post there anymore it's been so long this is back when beams engines and all that were being dropped into all kinds of cool cars doesn't matter what that is it Time gone by better engines and management systems beams 3 SGE GTE etc.

    Yes that's the adapter The model specific adapter that adapts your steering shaft splines to whatever steering wheel you want to screw to that adapter Grant is just a company I'm sure in your country it's called God knows what but I would hate to think that there's not a company that sells steering wheels in the UK but that's not what you want You're using Toyota stuff so you're going to be having choices of all kinds of cool steering wheels from supras to God knows what what are you working on a detomaso mangusta?

    No, one of my good mates is a De Tomaso specialist though! Mine is one of the F cars.

    Well there you go I don't think you'll have any trouble adapting the stuff you're trying to adapt and making it all play nice even the steering mechanism and whatnot should be pretty much a breeze to work with and you're definitely on the right track for the steering wheels because there's a lot of nice ones that Toyota made and it's a pretty popular spline shaft size I do believe so you should be in real good shape and pretty short order.

    Thank you - I'm also fitting the Toyota rack as the factory one - despite being an Italian car, was made in the UK under the typical economic manufacturing conditions of the early 1970's. In other words, it was produced on worn-out machinery to an out-dated design using the cheapest possible materials. Result: a poor quality part with tight and loose spots that wore out quickly. Even if I rebuilt it with lots of tender care and attention, it'd still be a second rate component. Besides which, if I sell the old one, it should more than cover the cost of fitting some well made Japanese replacements!

    No you're on the right track this is how lots of guys do it You've tried and true Toyota parts on a whatever it is you're making You're just making it better for the use you're going to put it to whatever that may be probably a good thing I mean even lotus and companies like that have used Toyota engines in there esprit. And cars and vehicles for the movies and all kinds of nonsense because people used to know you turn the Toyota for economical quality machinery now after 2010 you know all of these companies have gone to well you know. Thank God I'm not going to have very many more vehicles to ever have to buy I can get by on whatever but I feel bad for my daughter hard to trust Toyota even anymore That's pretty sad state of affairs at my judgment.

    I'm pleased to say that my new boss adapter not only arrived today, but it fits too!

    Excellent now from that boss applied to your steering shaft splines You're able to bolt various and sundry steering wheels to that boss? because usually the boss comes already built into the steering wheel in the Toyota when you grab a wheel from any Toyota from '85 up to at least the late '90s and probably early 2000s when you undo the 19mm nut and wiggle the steering wheel off and hold it in your hand you're holding that boss or hub adapter as it's well built into the wheel you can't take it off That's what I was trying to figure out how that was going to work. Because if you take the steering power assembly from the Prius with the shaft sticking out of it the spleen's are already there then if you have a Toyota steering wheel from almost any cars from years mentioned above it'll drop on the splined shaft. Without the use of any aftermarket boss but I guess there's something I'm missing but anyway I'm glad it fits so that means everything should work stellar.

    The Momo steering wheel from the car was held on by six 5 mm countersunk bolts - the boss that arrived today had three different bolt patterns built into it, one of which was right for my wheel - so it just fitted straight on!

    So you're not using a Toyota wheel You're using an aftermarket rim with one of the three standard common bolt patterns built into it got it The similar to the way my fittipaldi E3 steering wheel is made I guess that's how most steering wheels are made actually except for the factory steering wheels which have the boss made into the steering wheel That's great so you're off and running so here that would be called the multi-hub adapter I guess It can fit several bolt pattern hub circles onto this boss which is a good thing very cool.

    Yes - that's exactly right! The Prius rack is far too wide for the car though, so I've got to buy some shorter inner tie rods together with shorter rod ends. I've got a load of differently sized candidates lined up though, so once I've worked out exactly how long they need to be, I'll get buying.
