Default Vibration after 65 mph

I have a 94 mustang gt 5 speed that is vibrating after 65 mpg. I just replaced the whole rear end, and I am still getting vibration. The U Joints seem to be fine, BUT the other day I checked the output shaft on the transmission and there is a little bit of play there, as in I can move it side to side about an eigth of an inch. I am assuming that there should be absolutely no play there. Is it safe to say that that is the source of my problems?

That's the other issue. One of thetwo bolts that holds the transmission mount to the crossmember is snapped off, but it hasbeen like that for years. The vibration has only been happeningfor a few thousand miles. Therubber transmission mount itself still looks fine.

Does the transmission need to be torn out to replace the bushing?
