It appears if I did follow spec that the retaining ring might not go in as the stack would be too high.Everything that came out seems to be in good shape with zero wear.

I am not sure I follow you.... the old frictions / steel plates were OK, for clutch pack clearance?

New frictions and steel plates are too thick / high?

There are two frictions that will fit.... t-350 / powerglide and the 700/4L60 design.

700 frictions are about .090 thick.

t-350 frictions are about .100 thick

not sure if that helps or not.

I stack up reverse frictions and steels in the case on the piston.. set the center support in , check clutch pack clearance visually. I've done it that way for many years.

Yesterday is history.
