Just like to say I found a suitable rear end for the
panel project. I wanted a rear of similar width to
the stock with disc brakes, built-in E brakes and
3:42 to 3:73's. I also wanted GM and nothing smaller
than 8.5 10 bolt.
Turns out the Blazer/S10/Sonoma ZR2 off road model(around 96 & up) model had such a rear end. (3:73's) They were a shortened version of the full size pickup. The regular S10 only had a 7.65 10 bolt and was clearly not wide enough. The ZR2 width was 3/4" wider than stock.

The one I found was $560. tax in and in very good shape
including rotors, e-brake etc.

A downside might be the limited slip called Eaton Gov Lock may
be problematic if abused. Probably means staying way from
drag racing and excessive tire spinning.

Works for me!
