I have a 49 3800 flatbed that I am about to replace the entire rear axle with a more modern axle. My question is what are the axle widths of a 3/4 ton 67-72 truck and the axle widths out of a 73-87 model? My truck is a flatbed and I don't care to much if these axles are a bit wider. I just don't want and axle that is a foot wider. The 73-87 models will be the easiest to come by.
