Purchased a set of these headers a while back while redoing my motor along with a buddy of mine when it came time to install the headers on a truck with a 3 inch body lift we’re hitting the cab mounts off the frame on both trucks. The buddy of mine has even went so far to build new cab mounts got the passenger side to bolt up but the Driver side is 2 1/2 inches short from even touching the head. Just a heads up for all you ford guys out there mine is a 76 and I believe my buddies is a 78
