if your frame is good i would put a fatman front end in.they are custom made for your truck simple to do and you no not have to build everything to remount the front sheet metal or the cab and bed. comes with power steering and disc brakes i put one under my 35 and my wife likes the way it drivesand stops. if you want to use the frame you have get a tape measure and check out both frames for width in several places kick up at rad mount height bed kick up and where the body will mount. seen many a good truck die because of a frame swap but i have done it another way is to sub frame it with a 68-79 nova
