The long box fleetside box on our project truck has hauled more than its fair share of concrete and who knows what else over the years. As a result it needs lots of work, plus the tailgate is only good for scrap metal ( whats left of it ) .

I found another box complete with tailgate this weekend that is mint, basically just sand and paint. The frame its sitting on has the torsion bar front suspension which I believe makes it a 60-61? box. The only visible difference I see is that it has no provision for back up lights but when I check repro parts they list the cross sills for a 60-62 different than those from a 63-66. Does the box mount differently on the early trucks with the torsion bar suspension? I still have the cross sills from mine but the rear one is pretty bad. Anyone have any experience with this?
