So I found a 440BB

The big weight bolted to the tail ? Sounds like a "C" Body or possible 1/2 ton truck.

To clarify....It was a round balancer type thing not a weight on the tail shaft itself. I didn't look at it that close but I did notice it, I think that part of the drive shaft was still attached with that round balancer thing??
