I experienced something similar after the installation of no-hop bars, but I couldnt pinpoint it as being the bars because it was also a new rear end.. It very well could be though, because it changes the geometry of the rear end..I beleive they relocate the center of gravity which also changes pinion angle.. Im sure more people will reply, this could be a good one..
one last thing, the vibration is at high speed, not all the time and is extra bad when turning at high speed..
You can get a good idea as how adjusting the upper control arms in or out will minutely adjust the angle of the differential to drive shaft.

Per my e-mail I forgot to mention that I can "drive out" of the vibe. I use the Morrisson Hopstop bars which not only let you adjust by upper control arms thread but have three distinct holes to attach the upper arms to on the hopstop bars. I am driving on MT Et street tires too so the vibe can be exagerated by the balance( or lack thereof) of the rear tires.
