Anyone know what driveshaft(s) would interchange into my 68' Bird? I'm swapping the ST-300 for a TH400 and don't really wanna cut my driveshaft down. I have the TH400 driveshaft from a 74 Gran Prix, that my 455 came out of, maybe I could just have it cut down. But are there any cars out there that if equipped with the TH400 would be a straight swap?(Besides a 1st Gen. 'Bird...there are less than none in the boneyards around here as far as 1st Gens go.) Thanks. Jeff
