Is that the correct C Pillar? I thought all GMVs used the H C Pillar and weapon support
There are at least 5 or 6 different GMV C Pillars, from
A: one piece with 90 degree sides, angled forward with angled tubing strut, used with or without tubing cargo rails that are straight sided then angle inward the last 10 inches or so before the C pillar
B to one piece with 90 degree sides standing vertically vs angled forward, with spoons for the H style 6 point Weapons Support/LWS turret mount, with angled tubing strut, used with or without tubing cargo rails
C. One piece angled inward, angled forward, with spoons for M1025-series metal roof and 5 point (M1025-series) Turret Weapons Support, with brackets for sheet metal cargo panels
D. Three Piece, angled inward, angled forward with spoons for M1025-series metal roof and 5 point (M1025-series) Turret Weapons Support, with brackets for sheet metal cargo panels, converted from M1025 sponsons and crossbar. The sheet metal base bracket is triangular one side and L shaped on other
E. Three Piece, angled inward, angled forward with spoons for M1025-series metal roof and 5 point (M1025-series) Turret Weapons Support, with brackets for sheet metal cargo panels, appear purpose made, the sheet metal base bracket is triangular in front and in back of the bent tubing, appear to be purpose made for GMV
F. One Piece, 90 degree sides standing vertically, has spoons for M11-series plate metal roof, and 3 spoons for both the 5 point Turret Weapons Support and 6 Point Weapons Support, with brackets for sheet metal cargo panels
G One Piece, 90 degree sides, standing vertically, has spoons for M11-series plate metal roof, and 3 spoons for both the 5 point Turret Weapons Support and 6 Point Weapons Support, with angled tubing strut for tubing cargo rails.
The above are based on my own observations of original photographs and the auction videos and pics, and are not all inclusive nor are the A-G any form of formal designation.
Whether any of the above are TACOM or Support Company Maintenance manufactured/modified/converted is unknown at the current time.
You have to use the bolt holes in wheelhouses and the paint layers like a detective to figure out what was used on each truck, there is going to be no cookie cutter configuration other than close similarities within an ODA as far as keeping loadplans universal for paperwork reasons (USAF is picky, sure golden 40mm death eggs are fine on the aircraft but no propane bottles for your stove..lol..that must be why Kenny's team mounted the inverters to the roof for their drip coffee maker) and practical reasons during operations.
Books need to written about this little known subject.
