Zero welding experience, I dont even own a welding machine, but I have a friend who is a very experienced welded.
12 months? Thats alot. So a single cab disco on a defender chassis doesnt line up nicely? The (very brief) plan is to buy a defender 110 hi cap, and my discovery, and to take the body off my discovery, put the cab of the defender on the disco chassis (been done many times, is well understood, and quite easy?) And then with the leftovers, to chop the disco body (easy) put some kind of rear bullhead in (kit available on ebay, or try and weld the bulkhead from another pickup, e.g. ford ranger, l200, etc in to fill the hole) and to put that on the 110 chassis. One of them will use the hi cap bed, the other will have a nice custom tray/canopy/whatever. So, if the defender body fits on the disco chassis, surely the disco body must fit the defender chassis?
