Removed the drive shaft, had new u-joints installed, and had it balanced. No change.
I’m guessing it’s either the angle on the motor/transmission in relation to the rear end, or I may have to pull the motor/flywheel/pressure plate/clutch assembly and have it balanced. When I sit in neutral and rev to ~ 3000rpm, I’m getting some vibration, although it doesn’t seem to be as bad as when I drive. Here again I feel it at ~ 50 mph and up, but it is really noticeable when I let off the accelerator at those speeds.

It's relatively inexpensive once you get it out. A local place in LA costs less than $70. My '64 Spitfire definitely has a wobbly shaft, but I haven't made the time to pull it out and get it balanced yet. I stick to surface streets in the meantime.

Since I have my new Lithium pack, I've getting my 65 Datsun out on the highway and up to ~ 60 mph. Never did much of that before. When accelerating, I don't experience it, but when I let off the accelerator, I'm getting a pretty good vibration. Step back on the accelerator, and it goes away. Don't seem to notice it at 45mph and lower, but when going 55 - 60 mph. I just put new tires on it, and have had the front end aligned. Any suggestions ?
