Got my diff. all stripped at the weekend bar the pinion shaft which my friend pressed out for me this morning, good to have friends with a 60 ton press!
All good so far, I haven't cleaned the internals yet but they all look in good condition, just got to find someone who needs them and offset some of my expenses.
Side shafts were both good, no mushrooms on the ends and snap rings safely in position, the crown wheel and pinion are both genuine GM, if what I'm seeing is a date stamp they are from 1967 so must have been NOS when fitted or else the PO swapped out the whole diff from another car.
I had to helicoil one of the mounting holes as it was stripped, I did expect that as someone had fitted a nut and bolt in that hole but so far no nasty surprises.
While I was in my friends shop this morning I had him drill the bottom for a drain plug, I have a magnetic one on it's way.
