8 3/4 Yoke Issues, U-Bolts? Big Straps?

Why would someone do that? There is not really enough material on the back to let the nuts ride correctly. If it was drilled they did a pretty good job, they aren't wallered out or messed up. Had to have been done on a press, not under the car for sure.
So if I get a correct driveshaft with the correct u-joint and then change out the yoke, I will be good to go. That sounds expensive for something that should be so simple.
