I put a ez dumper insert into my 1998 1500 Z71 long bed. I know I need a 3/4 or bigger truck just trying to make due with what I got. I want to raise the back back up with overload springs or at a leaf I just don't know what I need. My main use with the dumper is leafs in the fall. Let me know what I should get and where I can get it and of course $$$.
