Yeah it needs to move towards the front a scooch, made the pickup bed frame, out of 4 c channel 1"legs and 2" wide, and some 1"1/2" x1"1/2 angle iron, bolted that in place also welded the rear cab mounts in place.
One picture shows how the side walls covers the frame just a little and the other shows the hight, it will stay even with the cab line.
That's my 70 year old grandpa that gave me this truck yes they were both made in 1945, the truck is his birth year, probably one of the last most fondest memories I will have before he goes will be spending time on this truck with him, he practically raised me.
Ps look at the last picture that was were the fender was hanging, it was holding it self up so I left it there so I could take the picture, if I moved it forward it would fall.
