I have a 1991 c1500 with the 5.7 and my drivers side Lear spring is sagging more than the pasanger by about an inch. I was thinking about swapping them out with some springs off a 2000 model truck. My springs are a 3 leaf + over load and the newer trucks are a 2+ over load. I don't do any towing so I'm not worried about any of that I assume it will lower the back a little considering there will be one less spring. I'm fine with that just want to know if any one has done this and if they will fit?
