from right to left

First, how much is a lot?

 

I would expect that to fall in the "labor of love" category, and probably be most practical if there is a good salvage yard nearby with left-hand-drive cars in it, or if you already own one or two of those as parts cars and just want to convert this other one for some reason. I suspect it would take very many hours to do.

But probably not as many as;

You'd have to rebuild most of the front end of the car and it'd cost more than the car is worth... The less expensive route, as in less than $3K is done by this company and others like them, but it's not very easy on the eyes: Right Hand Driving Systems for Postal Vehicle Conversion | PEDAL PROS

 

Why Even if you could do it yourself it would be very costly buy a whole front clip off of a correct drive car or a half cut would seem to be cheaper but then to weld it back together and blah blah blah laborr of love I don't know man. To try and do it piece by piece like that would seem to be kind foolish I believe. But if it's worth it to you go for it the older Toyota's used to come with the brake booster and master cylinder stamped on both sides of the firewall so you could move the old door closer type steering I can't remember the name of that type of non rack and pinion steering You could swap the idler arm and the steering box but you would need the steering box from the correct drive side car to have as cars got newer I think they stopped doing this so now you would have to get the complete different rack assembly All of that stuff all of the brake components like the master cylinder and stuff on the firewall that connect the pedals that might move over but then feeding it back to the ABS pump and accumulator could get pretty tricky I don't think you could bend the metal lines and stuff to do that so you would need the parts again from the correct drive car it could get quite silly very quickly so I would plan it out very carefully if that's what's happening You might find it cheaper to literally import a half clip or even a whole chassis.

 

Short answer: YES, it does cost a lot (both time and money).

Long answer: ABSOLUTELY! You will incur substantial costs with diminishing returns pursuing this endeavor.
