Wobble at 65mph?

My '73 has been wobbling in the back somewhere since I got it last month. 55mph is nice and smooth, 65mph sounds like I'm driving on one of those stips on the highway that are supposed to wake you up. Once I'm up to about 70mph it's gone again, all the way up to at least 100. (damn, I'm impressed my truck made it to 100! ) It doesn't have anything to do with engine RPMs, only speed.

Anyway, I thought my 33" tires probably need to be balanced. And the tread keeps picking up peices of gravel. Today I noticed that at 65mph the shifter handle on the t-case wobbles in tune with the rest of the truck. This makes me think maybe it's not the tires? Anyone have any thoughts? Could it be my drive shaft? For some reason the rear shaft is bigger than any other I've seen, like 6-8" in diameter. What's with that?

You can set my truck on fire and roll it down a hill,
and I still wouldn't trade it for a Coupe de Ville.
