2nd Gen rear-end for 3rd Gen
2nd Gen rear-end for 3rd Gen
I was wondering what the differences were (other than the obvious mounting differ) of the gen2 10 bolt 8.5" to the gen3 10 bolt 7 5/8. I read the 'how to' about the gen4 on the site and found they're 2 inches wider. I wanted to create a Hybrid rear-end to fit the gen3, so I won't have to worry about the 7 5/8 self dustructing. I'm sure someone has done this, so experiences good/bad are welcome. Also, I heard that the gen3 axle tubes are thinner...Thanks Art.

I have both a 7-5/8 and an 8.5'' sitting in my basement now. I was planning on cutting teh backets off the one and rewelding them to the 8.5''. The biggest problem, as I thik Vader pointed out, would be the torque arm mount. As far as dimensions go, I really don't know.
i think with wise they might be close, but the 8.5 2nd gen is a leif spring and the 3rd a 4 link, everthing would need to be welded up perfect or the car will drive wrong and the suspention bind. i wouldnt even attempt this, its a serious PITA and would be better to just get a eaton posi and some moser axles and be done with it. no worrys and it will hold up.

Instead of bumping threads so old the worms have come & gone and left nothing but Mold, perhaps search out threads where someone has actually completed this swap?
