8 1/4 sure grip

barracudadave67 said

Ok all
I aquired a 66 B-cuda that has an 8 1/4 rear end in it. it is not a "sure grip", but a one legger.
My question is..... what parts do I need to make it a sure grip,,,,,,,? I have no experience with 8 1/4 rears
All answers appreciated.
Thanks Dave

If you want a pure Mopar Sure Grip there is really only one choice, but there are a lot of aftermarket choices for the 8.25.

Here's a couple, but I just did a Google search for Chrysler 8.25 positraction.
I used positraction on purpose instead of Trac Loc or Limited Slip to get a wide variety of results.
Most all the major rear end companies have them for the 8.25 and various manufacturers and types also.
There is a shitload of aftermarket parts support for the 8.25, and then of course there is Ebay.
