U joint and pinion yoke issues
I’m having problems with my u joints and driveshaft. I have replaced many before but it’s strange on this car because the 8.5 10 bolt pinion yoke has no “pocket” for the u joint caps to sit in. I replaced the rear u joint with a Moog 534 and some new u joint straps and bolts. I torqued them properly and the driveshaft came off the car in 2 blocks! It’s as if the straps don’t clamp the u joints tight enough. Is the pinion yoke just worn out or am I missing something really simple?

The yoke is supposed to have tabs at either end that the u-joint caps fit snugly between. If yours doesn't have the tabs, you need to replace the yoke because either the tabs snapped off or someone "removed" them.

Also, you may need a crossover(?) U-joint meaning driveshaft is a 1310 size and since 8.5 yoke, 1350 size.
Larger 1350 has C-clips inside yoke, picture does not show in thread.
