1969 Swinger 340

I'm a dumbass, but not for the reason I originally thought. I woke up one morning and realized what I did. When I swapped rear center sections, I took the u joint straps and layed them under the car. One of them was a big yoke, the other was small. I managed to put the large straps on the small unjoint caps, and didn't notice. Swapped the straps and I'm back in business! Still needs more tire though:)
