Strange viabrations!

It's my '73 again! I must say that forums like this sure do help the hobby!! Anyway, she viabrates after about 50mph. I have a floor shift installed on the old 3 speed manual, and as the viabration kicks off you can feel it in the shifter lever. I've noticed two things it might be. First, the pinion on the 9" rear shows a bit of slop (it's not a u-joint), so the pumpkin probably needs adjustment. Also, well, the tranny is junk (se my tranny swap post). Any ideas?
Thanks, Polkat.

Check driveshaft and rear wheel balance.

it really sounds like a driveshaft problem. if it was the ring and pinion it wouldnt make a vibration but more of a humming noise.

Could be a U-Joint. Sometimes they staytight when you check them, but they are siezing up internally which will cause a vibration.
