I haven't had time to take the yoke off. Had new 472 gears all new stuff
including crush sleeve done by someone else..Have not a clue about rear
ends, or those shims...It might not be worth worring about at this time until I get engine in a take it for a spin..Who knows, I might have
to try something different..The leak is very small.. Will let you guys know
more in the future what takes place here...thanks for coments r dobbs
