check all your bolts. See if any are loose on the tailshaft and crossmember and stuff.

Sounds like something is out of balance...
Has the tailshaft been cut at all? See if you can find any sign of a balance weight missing from tailshart. The weights were only spotwelded on and it isn't hard to knock them off if you bottom out. Check to see the unijoints are all in good shape. A dead uni will cause a vibration. It could also be a worn main bearing in the gearbox.
...or not alligned correctly. A bit of crud on the mounting faces of the engine or gearbox will prevent correct torquing of the bolts. After a while things wear loose and that can cause vibration problems.

That should do for starters.
