Just in the process of reinstalling a rear diff housing in a 2005 350 Drw. I had to have new u bolts made up, as the originals were seized up. The u bolts i had made are 1/2 material instead of 5/8 material. Will this be strong enough, or should i order a new set? I cant use ford u-bolts because this truck has had 4 extra leafs installed, so factory bolts are too short. Any thoughts, and does anyone know the proper torque for the ubolts?
