I have a really nice differential, came out of a 1970 Pontiac Trans Am.
Will fit many other GM models of course, Camaros, and Novas etc.
for sure.
Has the leaf spring mounts still in place, but can be modified to work with coil spring suspension also.

4:10 gears currently installed, but can be changed to other ratios.
Will no doubt need to be gone over bearings & seals as been sitting in my garage for 40 years! Very stout rear end for a nice muscle car or hot rod! These are very difficult to find, especially complete like this!
Comes complete with rear drum brake set up.
I had removed for sandblasting and paint.
If ad is still up, this part is still available!!
Please only ask legitimate questions through craigslist email link and provide your phone number for text or call if you would like further information, pictures or to set up purchase.
Thank you for looking!
