Stop in for a cup of coffee

What’s it look like? Get a micrometer and give me the specs. My t56 kit came with dozens of shims of all various sizes. I can see if I have one
.640id x 1.125ish OD x .032 thick... i will look through my washers i can probably find one.. just prefer to have a flat shim, most washers are crowned. More annoyed than anything else though :) I can put the trans together without it and end up around .067 endplay which is in spec but pretty big.. i'm overthinking it again
