Hi im working on an old family heirloom. the specs are a 1986 gmc v-8 four speed with over drive half-ton, 4x4 long wheel base. used to have a 6-in lift. it wore out. no interior. drives though. going to restore it to my likes. making a new chassis out of stainless steel. im having trouble finding the old blueprints so i can make a new one in master CAM. can you help me?
