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

I can post some tomorrow. I got under tonight and when the bolts didn't work I called it a night. I also see another problem. The u-joint doesn't have any c clips and the yoke doesn't have the tabs to keep it centered. So I might have a few problems. The shaft I bought from a member on slant 6.org. It is a Ball and Trunnion conversion shaft with the slip yoke mod on the trans end. I need to get to the bottom of this. I thought this would be simple!
