MORE rear end noise and vibration

the Vibration problem is solved with the new drive shaft and bushing/seal kit installed and the new mount. The old slip yoke was scarred with many rings whre it should have been smooth. So the bushing was probably damaged too. The tool they made worked slick and I do not see where I was charged their time making it. Any high speed vibration now does not come through the shifter.

I may still have some bearing noise, but I'll know for sure when a wheel falls off or the ring gear exits the back, right???

"Have you checked any of the control arm bushings yet?"
Yes, they do not look great, somewhat smooshed and maybe a crack, but are complete.

"check to see if the mfflers are rubbing against the driveshaft"

They are fine and have plenty of clearance. But funny thing, when i was driving today, the hottest day of the year so far, the passenger side pipe got hot and grew in length enough to rub on some thick metal where it curves around the gas tank. IT SOUNDED HORRIBLE! The pipe quickly cooled off and was fine until it hot again. It will go back to the muffler shop that put my quieter super turbo mufflers in.

"its going to be the drive shaft bolts ...but i wouldnt recommend the poly"

The bolts were among the first things I checked. The poly tranny mount may transmit a little whine in second, but the old one was shot, and with other upgrades it still seems like a good precaution. But I will not do the control arms that way now you typed.

Thanks for those who tried to help, and especially to those who pointed me in the right direction!
