leaf spring u-bolt/plate problem

i'm looking at these plates.....I bet I can make my own....1/4" plate steel, with 1/4" plate gussets for the shock mounts....
basically just the same as the factory stamped pieces, but with the sides and bracing welded instead of stamped.....

then some 1/4x1/2 bracing welded across where the stamping is raised across the plate to prevent bending when the u-bolts are tightened.......
