Thanks. I basicly bolted it to the frame with grade 8 1/2 inchg bolts. The frame is shaped like this in the front ] so I drilled a hole in the bottom of the frame rail and bolted it up. and the back it`s the same material but it lays flat.
Sweet truck! I was wondering if you could post some pictures of how your bed is attached to the frame? Or you could just message me... I am looking at getting a 79, but the PO screwed up the flatbed and its going to need to be redone.
