OK, here's a pic of the yoke end and the bearing end, no where near in phase,
It's the one I took off my 68 coupe. The rear was a Chebby 10 bolt from a 69 Camaro, I assume the driveshaft is from the Camaro as well. I THINK the BOP rears had larger u joints than the Chev rears but I'm not sure, could be the original 68 Firebird shaft but I'm thinking 69 Camaro.

Where was the show?
