I am finishing up putting a new dif in my car with new series 3 eaton, 3:31 gears,all new bearings axles and seals. I spent a lot more than I thought I was going to so depending on what it is worth, I am thinking about selling the rear I am taking out. It is a 68-72 rear casting number 3917124 NF, date code 0927B. The axle tubes have been cut for C-clip eliminators. Axles have 3 inch studs. I had discs that I an re-using so no brake parts.I have a guy that has asked me to put a number on it but I don't know what to ask. He is not a friend so I want what it is worth. Thanks.

SHOOT!! Forgot to say 4:10 gears with Eaton posi!

I'd say $1000-$1200...at least that is what I'd be willing to pay for one
