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
I would go with cutting down the big car drive shaft. I am making the same swap in my 69 and am going to have the original drive shaft cut if need be. I think I have a short shaft TH400, so I won't have to, but I called around for prices. $30 - $45 was the range to shorten one from 4 shops. I was expecting more, but it's pretty cheap!
Post up the outcome when you get it done. I am putting a TH400 in place of I believe the car came with a TH350. I purchased the 400 front yoke from a Camaro parts catalog and haven't had the chance to look and see if the shaft is going to need to be shortened or not.
