Rifle stowage in 13 Cab CGT
 

Hi
Can anyone please let me have a picture or a diagram of the clips for holding the rifles behind the driver and commanders seats in a 13 cab Chevrolet CGT.
The clips for the two rifles behind the rear seats are present, so no problem there, and I can deduce where the butt holders go on the floor of the cab for the other four rifles but I have no idea how the upper brackets fixed to the side wall of the cab for these rifles, or what the brackets looked like.
thanks
Rick Overy
