how to look for a salvage yard rear posi?
 

I have a 70 chevelle with the 10 bolt open ended rear I am wanting to change that to a posi,locker what ever will get both wheels burnin at the same time. What I want to know is what kind of vehicals have the same size rear ends that I can look for a posi in to just swap in to my car and maybe save a few bucks. Thanks

guys in scrapyards know all about posi's no matter what car they come in.... unlikely to get any kinda deal.... but anythings posssible I guess

'68-'72 Chevelle or El Camino. The 'other' A bodies are different.

OR

You can install one of these. (I have one in my '33)
