I'm pretty sure the front crossmember will fit from any chevy 2 wheel truck up until the late 80's. It seems i remember reading that you have to drill a couple holes for the 73+ crossmember to mount to the frame. I was planning on doing this so i did some reading on it but i decided to just keep mine pretty much stock and maybe i'll go nuts on another one later down the road when i have some more money on tap.
