Need rear differential advice
 

I have searched this board for the last 3 days looking for an answer. No luck. So I thought I would ask for some feedback. I want to swap a different rear end under my 1986 c10. I would like 3:42 gears(approximately), limited slip, and disc brakes. Here's the question. Is there a particular unit that would swap almost straight into my frame? Same width, I could move any spring mounts etc. ie Camaro, Impala, 2000 c1500, etc. 10 bolt or 12 bolt????

I dont know of any...
But you should be able to research your measurments against the measurements of the stock rears you mention by doing some google searches.

Whats your budget?

Re: Need rear differential advice
 

I am cheap. However, for the perfect fix/fit, I could probably do $700 for a budget.

With that kind of budget, I would think that the 88-98 C 10, rear some new perches and some "race car" brake parts would get you there. This however does require moderate fabrication and welding. Jay

Just last week I picked up a non-posi 3.42 rear end from a recycle yard for $100. It was from a '88 Suburban that had just come in to be stripped. A Powertrax locker is about $330 from Summit and it installs easily at home with no special tools required. And for disc brakes, there are several complete conversion kits available in the $350-$400 range, or you can just get a set of mounting brackets for the Eldorado calipers and source all the rest of the parts yourself.

anyone have any reviews on the Powertrax?

Not to hyjack the thread....but, I was looking to do this same swap, minus the disc brakes. Is the 88-93 rear end the same width as the 73-87? Does anybody Know the exact wms to wms for these two rear ends. I'm sure this info would help out the the org. poster as well. Thanks.

My stock differential is 63.75" wms to wms. I found a 1990 Camaro unit with disc brakes. 3:42 gears, and positrac for $500. It is 64" wms to wms. Think I'm gonna jump on it.

That Camaro has a different wheel bolt pattern than your truck does.

Yes. I have access to a mill. I will redrill the fronts. So many more choices for wheels when you go to the car pattern.
