It measured exactly the same width as my stock rear end, which is what I wanted. All I had to do was move the spring perches for installation. | | | | | Joined: Dec 2003 Posts: 1,554 Shop Shark | | Shop Shark Joined: Dec 2003 Posts: 1,554 | Measure,Measure,and Measure again. | | | | | Joined: Nov 2008 Posts: 64 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2008 Posts: 64 | Alkay3
Could you tell me what gears you are running in your s-10 rear end?
Thanks

I checked a lot of them for their gear ratios, a lot were 3.73, but some were 3.08. seemed to me the 3.08 gears were in the latter trucks, with the 4.3 motors. At least that's the way it seemed to me. I used the 3.73 in mine, w/ a T-5, and 261, works great.
That's good, tighten it up till it strips, then back it off a quarter turn!
