Truck's Gotta Bite !

Getting our '80 D150 to hook up. Sorry, we aren't spending money to do this. So, I'm using my "thoughts" to what's needed. Part of my thought is the axle is centered, unlike a A-body. 2nd, with a long bed and a light back end, weight transfer seems difficult. So I'm digging through junk trying to create what I think might help. LOL. Goodness, train wreck i can tell...
