My truck is mounted on a 78 ton frame. I used the old frame to fill the gap between the floor pans and the 78 frame. I cut the old frame to the contour of the new frame and welded it in place. Your fenders are the large truck fenders and would probably fit better than the small truck fenders but I have not measured. I was thinking the width was the same or only slightly wider. The wheel opening is bigger which is obvious. Find a 1/2, 3/4 or 1 ton truck to measure that is near you so you can see for yourself and get an idea of how the truck will look with the bigger sheetmetal. Keep in mind that with the larger wheel opening the rear fenders have the smaller opening which may clash with each other. (if you put a standard bed ln your truck)
Search through my posts to see more information on my truck and look through my webshots photos. I have a picture of the wheels looking parallel with the truck in one of my albums. Good luck and have fun.
