I have two and half of them, plus a V8 bell and a /6 bell and the shifters, linkage, clutch parts etc from a truck sitting in my garage awaiting transplant into the Cuda. Whole mess of stuff I bought off a seller on Ebay for like $200 for everything.

Not really valuable as most think it's weak, with too wide gear rations and first too deep. But if you look at what's coming out today, deeper first, weaker trans, etc.
