I have one more question. In your rebuild writeup, you said not to mix and match steels from the early to late 700r4 reverse input. I found my reverse input had a wave instead of a belleville and the clutch clearance excessive. I ended up re-using the waveplate and adding 2 extra thick steels along with 3 standard thickness turbulators to get the correct clearance. Note it does have the later aluminum piston as opposed to the early steel piston. Will this cause any issues?

Another oddity about this trans is that it has what ATSG lists as the '93 low carrier support (.250" thk) along with the 725 low/reverse piston. This didn't seem to cause any issues with my stack height, and I reassembled with a 550 piston per recommendation.

By the way, my new 3/4 stack is M30 (6x .106) and my sunshell is M32 (late reaction shaft and thrust bearing).

This is all slated to be used in a '70 2-dr Caprice with a 413 CID small block and 3.73 gears.
