I'm accepting delivery of a 2006 Chevy cab over tomorrow.. It has a 16 ft box on it, and a 1600 lb lift.. I want to put some doors on the side for hose reels, controls, sprayer engine access, ect.. How? Do I need to find some factory alluminum ribs, and rivit them in around the holes that I cut? also, are there any door 'kits' that might have j-channel and such, so it still looks professional? Any help would be appriciated..
