Re: driveshaft legnth

The th350 has a longer tailshaft something like 4" I think. Someone will correct me with the proper size difference. But the th400 is definatly shorter

Re: driveshaft legnth

The tailshaft length is different, yes. But a t-400 is longer overall. So if you are asking can you shorten a t-350 driveshaft to work with a t-400 yes.

I suppose the you mean the actual tube itself?I believe the yoke that slips on tailshaft is different and the 400 uses the larger u-joint anyway?

Re: driveshaft legnth

Just need to shorten your shaft and change the yoke for one that fits a T-400.

Hey, does anyone know the legnth for a stock setup for my BB, Muncie and rear for my 70SS? I will add about 1" of height to the front end coil springs for the back in the dat look.

Thanks
