81-93 Ramcharger Roll bar is a 5 piece bolt together unit. It will not fit the 74-80 RamCharger/TrailDuster. I can be altered by removing 3" inches from the bottom mounting foot area & rewelded back together. Also the Roll Bar side mounts at the upper inside quarter panel are not there on the later RB. They will have to be made up along with the upper inside quarter panel mounting area on the body structure. If you have a MIG these will be simple modifications.
The later Roll bar is larger in diameter than the earler version. Photos are of my '74 TrailDuster with the above modifications preformed on the later RB.
