Well, I'm actually building this from scratch. I want to use the light-duty(1/2-1 ton) front sheet metal. I wanted to use the 1973-1991 frame because I have a 1977 1-ton cab and chassis frame with a 84 cab to axle measurement, but I dont think this will be heavy duty enough for my needs. I also considered the Step-van frame, but I'm not sure if it'll be sufficient for my needs. When I thought about it , the 2-ton frame came to mind. I'm also debating whether the 5/10 lug IFS frontend would be sufficient or if I should just "step-up" to the solid axle 5/10 lug setup?
