The weight on the tranny is to help with gearshift vibration as I recall.
Others have had excellent suggestions. One thing I'd like to throw
in the mix is: "what is the frequency of the vibration?". If it's a
wheel out of balance or out of true it seems like you'd have a pretty
low frequency vibration. I just replaced a failed U-joint on my TR-4
racer and that one was a pretty high frequency vibration - in my case
the vibration quit when I was off the power. The frequency of the
vibration will depend on the RPM of the out of balance / out of true
thing that is spinning. Driveshaft spins faster than wheels do.
Not sure if that helps, but food for thought.
