Nooo, but I have put an '85 four door on a 93 regular cab frame, and a 77 regular cab on an '84 Cab and Chassis frame, and an '84 on a '76 CC frame. The front cab mounts and radiator mounts should be right, but the rear mounts are gonna give you a fit. And the frame has a hump in it starting over the rear axle, but you may be in front of that with a little shorter cab. I built a crossmember out of 4x4 square tubing, and mounted that to the frame, and then mounted the cab to it. The 4 door had to be lifted to clear the hump in the frame, so I used a 2"(or was it 4"?) body lift on all the cab mounts. That worked great. Be sure to use the Energy Suspension neoprene mounts! They are tough as hell! I still have the '84 mounted on the 76 frame. It's mothballed in a barn right now. I've got the cummins and transmission for it, but not the time. The cab mounts sat right down perfect, so your's should too. If the cab will sit close to the frame like it should, you might could use some angle iron or channel to build your rear cab mounts and bolt them to the frame. Good luck!
