8 3/4 Rear Axle Tube Diameter

I'm doing the same, a Ford Rear, and have the perches, and just like you ground down the edges to comform to the tube curves. Now just need the mounting plates. Did you have any issues with the U-Bolts when you squeezed? I know it's only like an 1/8" of inch of each side, so guess that wouldn't hurt anything :).

Thanks.
