Thanks for the comments. I never really suspected the transmission as there is no vibration in the floor shifter at all. I know that it is bolted to the floor pan but if the transmission was at fault, I would think that I would feel some vibration on the shifter. I jacked up the rear end of the car and put 2 good size jack stands under the differential so that the car was well supported. I stated it up and ran it up to 70 mph.... no vibration. I found that to be very strange. I looked at the tires and wheels turning at 5 or 10 mph and there did not appear to be any up-and-down movement at all. One wheel did have a slight side-to-side movement of about 1/8". I plan on taking that wheel to a place that can straighten it out. The tires are new Goodyears.
I got the new wheel bearings on Friday but I didn't have a chance to change them yet. I know that a wheel bearing will normally not cause a vibration but since one is finished, I decided to change them before going any further. As I said earlier, the new front U-joint doesn't move as freely as it should. The ears on the drive shaft seem to be a couple of thou too close to each other. After changing the wheel bearings, the next step will be to remove the front U-joint and see if I can free it up.
A good friend of mine has told me several times that the Cragar SS wheels with the oval stud openings are the problem. I hope he is wrong as I really like those wheels.
