Wanted to give everyone an update on the vibration problem.
Took it to a local mechanic and put it on a lift.
He raised the rear end and had me rev the motor while he was underneath. I
tried 3rd and 4th gears and both were the same.
Vibration became very noticeable at ~ 1500 rpm. When I drive it
In reference to your P.S., good idea.
I'll give that a try and report back on the results.
Thanks;

Sounds like you are doing the parallel shafts part correctly. Does not matter
if the vehicle is level, just that the shafts are parallel to each other.
Are they parallel side-to-side as well? This is a bit tougher to measure, but
it is as important.

U-joints _require_ that the transmission be
parallel to the rear-end pinion shaft. They can
of course be offset, but the input and output
shafts must be parallel to each other. You get vibration otherwise.

Removed the drive shaft, had new u-joints installed, and had it balanced.
No change.

Even more common is bad universal joints in the drive shaft. Check them by
reaching under the car and twisting the shaft by hand, you are seeking some
slack but just barely enough to feel. and not much. If you can see the
movement it is too much. Luckily, the replacement of the joints is easy and

I'd try balancing your driveshaft. 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.
