Spicer Rear Alignment Shims - Key Questions!

UPDATE: These are by MOOG not Spicer!]

In another thread, @The Critic used NAPA-numbered versions of SpicerParts alignment shims, heavier duty than the typical SPC shims for fixing rear alignment.

I'm needing to go down the same path, but running into roadblocks.

I found the NAPA P/N's:
* 2643055 "up to +/- 1/4 degree Camber & up to +/- 1/4 Degree Toe"
* 2643056 up to 1/2 degree
* 2643057 up to 3/4 degree...
* 2643058 up to 1 degree

BUT...
1) I don't find anything like this at spicerparts.com -- do we have any idea who actually makes these?
2) I find no instructions anywhere, and no calculator for needed settings to accomplish specific adjustments. Ideas?

And finally, specific to my situation:
* My rear toe is currently way out on the right but ok on the left. Am I correct in thinking I can adjust both a bit to obtain the needed total toe, and THAT is what actually matters for toe? (That's what I'm understanding as I read.)

(In my case I need to do -.5 camber, +.5 toe on LR, and =.8 camber, +1.0 toe on RR.... so a 1/2 and a 1 degree shim for L and R....)

OH: I see that NAPA gives these P/N's as alternates for the SPC shims. Might SPC instructions AND settings work for these very-different shims??? If so, I'm confused since SPC is just one part for all angles. These are different.

 

Additional info: AFAIK, these shims are actually MOOG K6660-1 -2 -3 and -4 -- they are available from many sources (Home Depot !!! sells them for under US$7...)

According to one comment at the Moog site, a chart comes with each shim showing the breakouts needed for any particular setting.

SO, perhaps someone needs to take a photo of that chart? I'll search online to see if I can learn more...

UPDATE: Rear wheel alignment, need help with the shims | PriusChat gives more insight... and a scan for part of the (?? -1??) version

UGH. That scanned sheet adds confusion not clarity. Each box in the chart has a large number top-left that's the shim number to use. They go 1 to 6. But only 1 to 4 are sold?!!! And the discussion thread there shows that even the templates are way off...

Anyone who has futzed with this and succeeded... insight would help!

 

What a mess. PLEASE IGNORE THIS THREAD. I'm reposting with a more organized and accurate presentation.
