Thanks for reminding me about the FAQ. That makes total sense. The FAQ is super useful when you remember to reference it.There is a good link in the FAQ that discusses the differences between the years and sizes of those.
Thanks. That’s good information.![]()

All same size, just different thicknesses. Are 80-90 knuckle stud patterns larger?

I plan on reusing, but measurements show I need a .2mm (I don’t have) with the existing .5mm for the bottom thickness.if the shims are in decent shape when dis assembled, I've never had an issue with re-using them as long as they weren't "messed" up taking them apart.
I also have a bin with shims I've never used thru the years, just in case.
Yes the later knuckles have a larger bolt pattern.All same size, just different thicknesses. Are 80-90 knuckle stud patterns larger?

Noted. I'll see what my local dealership can come up with. Thanks.I usually order the shims I need from Toyota I don’t like the shims that come in the rebuild kits the Toyota shims are beautiful,,
and you can order the thickness you really need.
