741 x housing

BTW.. Dr. Diff has all the seals and **** you will need, and he only sells good parts...
I dont know about "all"...... hes a good supplier, but when i bought stuff from him, it would seem there was an assumption that i was working on a '65 and later even tho they require your model details.

The OP should also be aware.... he has shims setting the end play.....dont confuse them with the steel seals on EACH end of the housing.....youd have a hard time finding new ones if need be.

Best of Luck, Lefty71
