69 superbee vibration

[Sublime12]

I have a 69 superbee 4 speed with a vibration. I just replaced the u joints and had the driveshaft balanced. It seems to be under no load at low speeds, and more persistent at higher speeds. I have a little play in the slip yoke in the rear of the transmission, my thought is maybe the bushing in the tail shaft is worn, any suggestions?

Also, if that Super Bee has the big assed front drum brakes check to make sure one of them hasn't thrown it's balancing weight. If it's gone it will have left a rusty square picture of the old weight.

I know your car is a 4 speed but my Dart has a 727 and the bushings went bad in it and I got it rebuilt and all the vibration went away.

I never thought of a weights on the brake drum. Thanks for the replys. I'll check them out tomorrow.

You'll have to be more specific and have lots more detail if you want to get a clear answer.
Otherwise you'll be doing all kinds of nonsense and getting nowhere, but helping your local economy
