Anyone here ever measure their front leaf spring u bolts? I am getting ready to install my Skyjacker leaf springs, which I had laying around the garage for awhile. I need to replace the u bolts as well. I measured 3 1/4" W x 8 1/2" L on the drivers side. 3 3/4" W x 8 1/2" L on the passenger side. This is on a 93 W250. Can anyone verify this measurements on the u bolts? I wan't to make sure I am ordering the correct ones I am going with 9/16" u bolts, instead of 1/2" TIA!
