With you guys pointing me in the right direction, I crawled under the Model A after work tonight and the problem causing the vibration is obvious. The transmission points slightly down, and a straight line from it would hit the ground a little behind the car. Rear end also points down, tho' not as much, and a straight line from it would hit the ground in front of the car. Driveshaft is 22" long, including u-joints, and trying to sight along it while laying under there, it looks like the u-joints may not be perfectly aligned, either. Oh, S.O.B., what a mess. Do you guys think a CV joint would help ?? Driveshaft would have to be cut, but then they could align the u-joints, and balance it, too. The way the thing is set up, I hate to try and cut the rear end loose and re-weld it, and the engine/trans are way back in the frame and I doubt if I could lift the tranny. In 6 months or so, I hope to put a proper custom frame and running gear under it, and move the engine/trans forward where they belong, but I'd like the use of it till then. Whaddaya think ?? Starting to wish I'd never bought this thing. I haven't found ONE thing so far that was done properly - in the whole damned car ! ! ! What a mess.

Disgusted Lar.
