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

So here is my issue, need some help from the experts. I have a 741 housing with a 3.55 Sure Grip. I got it in a trade. I started to hook the driveshaft, 7260 U Joint, and the yoke didn't have any straps so I went looking. However... the yoke takes U-Bolts. I purchased some Dorman U-Bolts (81002) that were for 1.062 Caps. The problem is they bottom out before they take up. I looked at the yoke and it has this on the back of it: 072640 and RMASTEEL. My Question, does anyone know who makes the yoke? What U-bolts do I need to find? I really hate to drop the pumpkin and work the yoke issue over a couple of bolts!
