Well after having the U-Bolts on my 90 Blazer continuously loosen up I finally bought a set of new ones. I bought the Pro comp U-Bolt kit PN- 58301 which is designed for the 871/2 to 90 Chevy Blazer, Jimmy, and Suburban. The pro comp catalog list that states that the U-bolt length is adequate for stock and aftermarket leaf spring packs. Upon installing them I noticed that they are way to long. My question is can I shorten them by cutting them with a hack saw? I really don't plan on removing them anytime soon. Dan..
