Hi guys...As you can see I'm a newbie here. I got my M813 about a year and a half ago and am thinking about turning it into a deep water fordable GT. Are there any books or websites that would give me some facts about doing that? Also any lists of the names of GTs as I'm going to build a tribute truck and don't want to step an any toes. Is there anywhere that I can get the extended air intake, rear axle lockers, and the rest of the gear to make it like the ones the marines used? Also was there ever a deep water fordable gun truck?
