[ERASER5]

You do not have a 10 bolt. There may be 10 bolts holding the rear cover on, but that does not define a "10 bolt." A "10 bolt" is a GM 10 bolt 5 lug 1/2 ton axle and it is the weak sister to the GM 12 bolt. No 3/4 ton axle is a "10 bolt."

The Dana 60 has 10 bolt on the rear cover but is far, far stronger than a little 10 bolt. If you have a Dana 60, it has resale value. The rear drive shaft should stay with the Dana as it is the correct length.

I do not recall how many bolts ore on the Eaton rear inspection cover, but the front of an Eaton is bolted on also like a ford 9" diff. The drums may have resale value if they are in good shape. Same goes for the third member.

See my previous post about drive shaft lengths.
