This past weekend I wanted to try my luck at lowering the truck a little. I hope I am not the only one this happens to, but as soon as I start on something I find something else that needs fixin. I started on the rear leaf springs and noticed that the "U" bolts were all but wore through. I looked at all the local parts stores and no one carried the size I needed. But I did find some supper nice folks at a local company, Custom Springs who made me some new ones and only charge 9 bucks a peice. link to there web site
