Where do I find SM318 pilot thrust washers

[ayetav]

Hey all,

I inherited my great grandpa's 66' C10 Stepside. I was going through and replacing all bearings seals on engine/trans which is the original 230ci and Muncie 318 trans. I have just about everything on the trans put back together, but I can't seem to find my original thrust washers and they aren't included in small parts kits or rebuild kits that I can find.

Does anyone have idea where I can find two thrust washers? Parts 11 and 12 from attached part diagram

Hey, those don’t seem to include the actual thrust washers that go between the two sets of needle bearings. Unless the brass ones I received are just the wrong size

EBay has them.

Ah that is amazing. Thank you for your help. I guess the right way for me to find them next time is dig through the parts catalog which I have now found!
