With 2 different driveshafts? The underside of the car had oil slung all over it from the yoke seal leaking. So I replaced the seal and replaced the driveshaft thinking that would fix it. It fixed the leak but not the vibration.
I didn't drive it much with the original BOP 10 bolt, so I can't say for sure if it vibrated with that rear end. It was wasted so I swapped to a Ford 9" from my old race car. Its possible the pinion angle is now off. The 1330 yoke on the Ford 9" will accept a 3R Ujoint, so I used the factory driveshaft for awhile until I could get my aftermarket shaft cut down 1" to fit the TH400. My other car had a TH350.
Anybody got a good method to verifying pinion angle? I've got the upper arms adjusted to stock length, but I just realized the upper ears on the Moser housing may not be in the exact same place as the BOP housing....
