I have a 1997 Chevrolet 1500 2WD with the 5.7 Vortec. I purchased a set of Hellwig helper springs. I bought them from Summit racing for my year model but they will not fit if I am understanding how to install them. The adjustable end lines up with the bracket that holds the spring pack together and so I do not see anyway to get the U-bolt on. I have take a pic but I do not know how to post it here.
ive got the same helpers on my '97 1500. not sure what you mean by adjustable ends though. mine were easy to install. just removed stock u-bolts, stacked new springs(they have a pin that set into a hole on the seperator block for alignment), then replaced with new longer u-bolt from kit.
