The Stovebolt Site Forums The Parking Lot Big Bolts Building my diesel Franken' Truck

I've brainstormed quite a bit and figured my cheapest/most unique non- CDL way to go is to use stuff I've got laying around the farm. So what I have is a 48 GMC 1.5 ton (no engine) and a 79 Chevy C70 diesel with a 4-53T Detroit/5 speed tranny with 70,000 miles. I was wondering if I could use The Detroit, the C70 rear axle and my original frame? With the C70 rear axle (2 speed) would I still be able to use it with no CDL license? Feel free to give other ideas, tell me what will work and what won't, but keep in mind this is a low budget operation. This project won't be in action for at least another year. Also would my original 3 row radiator be sufficient for cooling this engine?
