narrowing a rear end

i have a couple 8.2 10 bolts hanging around out of my dads 68camaro i can take. im puting a pretty stout v8 in my truck and im afraid the rear wont hold with posi and some little slicks. so i think might take the 8.2 68camaro rear end and get it narrowed to teh stock s10 width.
does anyone know how much it would approximately cost? and has anyone done this before?
btw i dont carea about the leaf perches cause im going to bag it soon so they wont be on. its a 84 s10 jsut ta let ya know

Re: narrowing a rear end

The best thing I can tell you is if your going to make enough power to break the 7.5 then you'll be breaking the 8.2 IMO. You can narrow a 8.5 to stock s/10 width but it will require someone withe the correct alignment tool and professional welding skills. Take a early 8.5 say a (camaro trans am rear) procure 2 ....28 spline axles out of a 2wd s/10 and have the axle tubes narrowed accordingly. A little known fact is that the long axle on a 28 spline 4x4 s/10 is a bolt in (except the metric studs) for 8.5 Nova early Camaro rears. Hope this helps you.

Re: narrowing a rear end

or you can look around and pull a 8.5 10 bolt from a s10. They have 30 spline axles and are pretty strong. I run a 8.5 in my truck with a spool and stuck axles....

Re: narrowing a rear end

no astro vans have the 7.5 rear. 72 up to 77 chevelles, 72-75 novas, trans ams and camaro's 72-81 + some of the nova clones like ventura,omega etc. are some of the cars you could look for to get a 28 spline 8.5. The trans ams and camaro's are more likely to be posi than the chevelle and nova rears.
