I just started on my 51 Long Bed to S10 swap. I weighed all the option of building the original chassis or to do the s10 swap and opted for the swap. i bought the EZ Chassis swap kit and communication with Ed the owner has been GREAT! As with any build you need to have some fabrication skill. I bought a Ex Cab 97 S10 being I am building the long bed, but as someone else said Regular Cab long bed is what you want for the short bed AD. I have gotten my s10 stripped down now to the chassis and plan to begin the cutting and mocking up of the EZ Chassis brackets. Good Luck and do what you want to do with your truck. I get a lot of flake for my sway being I am taking away the 3/4 ton ability of my AD... to me these are hot rods and will only be hauling Butt, ezups and ice chests to the local show. I bought a Newer GMC 2500HD for my hauling needs.
