I wanted to change out my 3.08 for something better, two years ago, I was considering all types of options, then when I was looking around the Bloomington gold swap meet, I came across a 1973 big block corvette Rear Diff, complete with the cover and axle stubs. I checked it over and found no issues with it. It had hardly any play in and out on the axles. It was a 3.55 set up and bought it for $300. I swapped it out with my old set up and luckly it works great. I also noticed it has beefier parts inside and the u-joint caps were stronger. You might be able to look at swap meets or ebay for a used rear in good shape and just swap them out and seel your old one for nearly the same cost as the one you bought.Tumarr38758.8706481481

When you change the diff lube, don't forget the friction modifier additive for the posi.
