ha! I've just been through this hell. Are you talking about having just done your Pinion bearing and seal and rear drive shaft uni joints?

Vibration through the floor and seat base is classic drive shaft balance symptom so it could be this.

If you did your uni's and there is a chance you didn't put them back in with the same alignments, you could have an out of balance drive shaft. I learned this the hard way...
