I bought a complete rear 3.55 posi axel from frank's he said it was being used everyday in a car of someone he knows, and was in great shape !!!with shipping it was $850. when I got it in the car bearings were shot, IT sounded like grinding marbles When I called him. He said "OH WELL THATS WHAT YOU GET WITH USED PARTS".He also said thats why he dosn't sell engines of other large parts.
