I bought an 88 G20 that I want to convert to 4wd. I've been searching for a couple of weeks, and maybe my search skills aren't very good, but I haven't found any good detailed pictures of the leaf spring mounts for the conversion. How are people mounting the front spring hangers and the rear shackle mounts? I wanted to run the 46" leafs I already have&, but is another length better to get around the curve in the frame? I tried to contact Boulder offroad but they aren't responding, is there someone else that makes a kit for the Chevy van? Thanks.
