You might want to elongate the holes in your shock plates. I had to on mine because the 8 1/4 axle is slightly larger in diameter and even if you compress the ubolt to fit the shock plates it will not sit right on the axle..

I am running the correct 8-1/4" shock plates, the baby ones got tossed to the side, I should have mentioned that. The u-bolts would never slip over the 3" axle on the 8-1/4 if they were compressed to fit a stock 7-1/4" shock plate.
