The rear of my frame on my 62 GMC 1/2 ton panel looks exactly like the green cab 60 or 61 chevy in my example picture, except that since it is built on the short bed pickup chassis, to get the 7-1/2' bed, it has frame extensions slid into the frame rail channels and riveted in place with some serious heavy duty rivets. I think it might be two pieces actually, and the rear piece steps down just a bit. I can maybe take pictures another day. I think this is the only difference that I can see at least from comparing that picture.

The picture with the body off is a slightly different frame than mine, due to the different bracing where the frame mounted gas tank would go. I think the main parts of the frame are the same, just different rear bracing.

the fact that the frames are extended to the rear on mine makes me want to try and add some vertical stiffness by doubling the height of the frame with some C-channnel up to where the frame is boxed, and maybe make some type of triangulated gusset out of plate steel on one side of the rail. I was checking out a late model GMC frame, and the rails were more than double the height of the 60-66! I think they were just a C and not boxed, but still, that's a huge frame! That and the fact that I have coils in the rear makes me wonder how much tongue weight this thing could really take. With leafs, you have half of the support from the springs at the rear of the frame. With coils, the frame is just hanging out there where the trailer load is pushing. I am happy to have coils though, to give it a more sporty ride.
