So, I've taken my broken transaxle off (off to Daryl when I get done
packing it for shipping), and want to take the opportunity to do any
possible PM that allows. I'm going to replace the engine rear main seal
(seems there might be a small leak).

I checked the endplay, it comes out to .006", the wear limit. I
understand the reason it's ill-advised to adjust end play on a used
engine, because you may be measuring not just end play, but play
between the main bearing and case. I thought perhaps I could use some
plastigage between two of the shims to measure the "real" endplay and
make sure I don't end up clamping the crank to the bearing.

Comments? Oh, 2.0 aircooled (CV) engine.
