Brad Usually as the speed gets higher the vibration will get worse if its a drive shaft issue... what size tires are you running and are they balanced.... is it under load only or if you roll out of the pedal some is it still there

I had one of those weights that are on some tranys that bolt to the tail housing and it got rid of alot of the vibration but you can still feel a tiny bit at 85-90 mph.like i said it did get rid of alot of it though. one of the drive shafts i ahd made 1330 joint up front and 1350 in back the other is one i bought from a member and had it shortened it has 1350 joints front and back. this is with a 904 trany.thanks Brad

Brad How far out is the front yoke with the car at ride height.... shouldnt be any farther than 3/4" max
