I took the unit apart (major components)
cleaned everything in stoddard, put a new yoke seal in it. and put it all back together.
the ring and pinion had been replaced some time in the past. (I've had the complete section sitting in a milk crate in my garage for the last 8-9 yrs.
the gears are FOMOCO brand units. and look very nice.
If you'd like pics I'll be happy to send a bunch and every side.
I took it out of a 65-66 gal in 2004? I think. It was a 289 and three/tree car.
if I remember right.
Give me email address and I'll send pics
