M6 Bomb Service Truck information.

Hi Colin,
I agree with you that the 'plate' between the riser and seat could well be the 'Angle seat track'. Its a bit of an optical illusiion. Once you start looking at it as a vertical , not horizontal plate, it makes more sense.
So now we have a part number for the seat riser panel -5809802 from GM/Chevrolet Canada for a 1543 and also part number CV-471037 for a M6 from US Ordnance service parts catalogue. What we now need are photos and dimensions of the parts for comparison.
One thing I have noticed is that there seems to be a smaller gap between the fuel tank frame and the edge of the cab floor compared to 1533X2 cabs. Does this indicate a smaller cab width on the M6 or larger fuel tank frame? Also attached a recently renovated M6 riser panel and fuel tank frame. Interesting to see how wide the flange is on the sides and the fixing bolt hole locations.
