Hey just wanted to put this out there, i found this after many many questions and what i was told was here say. Its a third gen build up artical, the main thing i was looking for was the rumored 3.73 rear end out of a blazer that would mount right into our third gens, well here it is a 2.8L V6 blazer, supposedly some had that gear stock.

1987 Chevy Camaro Intake, Exhaust & Fuel System

Just scroll down a bit its there think its near the end of page one but over all this is a great read

 

I dident read the article but blazers never had a torque arm or springs. It is not a bold in swap.

 

if your looking for cheap gears... that them... really alot of s-10s came with 3.73 and a little higher even

 

Cheap gears maybe, but the entire rear can't be swapped.

 

The carrier and gears ARE bolt in. Series correct, anyway.
