Fellas -

My 68 RR (hemi, 727, Dana 60) has some driveline vibration at about 60+ mph. Wasn't happening until recently.

Lubed the u joints (I need to swap to solid u joints) today, checked u bolts for tightness. Got pulled over on the test drive (he liked the car, no ticket), but still vibrating.

Car does not have a pinion snubber. When I got underneath, I saw where it looks like the very rear of the driveshaft smacked the floorpan - must have been an extreme angle. My guess is that I tweaked the rear u joint when this happened.

My plan - drop the driveshaft, get solid Spicer u joints installed. Install a pinion snubber. Driveshaft stuff I can handle, but any ideas on a good pinion snubber? Doesn't have to be 100% correct Mopar; car is slightly modified, and it's not going to be concourse judged.

Thanks,

Scott
