I have a 66 GMC 1/2 ton long bed.
I am converting the trucks suspension to 3/4 ton mainly for braking and hauling reasons.
Yes I know the frame is still a half ton and understand all that. I pull trailers and don't like getting pushed through intersections, etc. hence the change.
As soon as I figure out how to post photos of the build ... I will..
Any other GMC guys here?
