I am just wondering if seller knows what he is selling. I am looking for a correct driveshaft for my XR7-G, but my parts book tels me the axle for 390/428cj w c6 is 49 41/64 inces. ( part # C8WY 4802-B ) The tape mark on the axle in the auction says 67 Ford and the seller measured it to be 55 inches... It is hard to believe this came out of a Cougar 428CJ.
On the other hand, if someone here should read this and accidentally have a correct drive shaft for a 390/428 w C6 Cougar laying around taking up precious space I would be more than happy to help you get rid of it.
