Good point. I'll check it again when we put it up on stands to run it at higher speeds.
I have found a shop that make axle shafts for racecars and I'm probably gonna have them make me some new ones here before long. Unfortunately, they don't make driveshaft, so I'll have to keep looking for that.
After having checked the axle shafts (again) and also checking the play in the differential, we noticed that the shaft splines had some play in the differential, maybe a little less than a millimeter. Though this was a point of concern, I didn't have much choice than to re-assemble everything and come to terms with the fact that the vibration might never be fixed.
That is until we clamped a hose clamp with a small weight to the drive shaft (read in this or some other mustang forum that a guy had done this). We measured the "wobble" in the shaft which was about 1 mm, and then added the weight on the "low" side (the inside of the wobble). Took it out for a test drive and the vibration is almost gone. So now I have found a place in town that can balance driveshafts (not too common around here), so hopefully the problem will be permanently solved.
Thanks to everyone for all your tips and help. I really do appreciate these forums :-D
man i hope for you and me that balancing the drive shaft fixes the problem because i have the very same problem and i have done everything even have the drive shaft balanced a wile ago and i was not sure if he did a good job
