Does anyone know where I can find the C-channel? that supports the door window in a 1966 C-10? Neither the assembly manual or on-line parts stores seem to have this piece. I thought a new window regulator would come with all the parts necessary but no, and I can not seem to find anything about it. I need to install a whole new window assembly in the drivers door and am stalled trying to find this one piece (let alone actually installing everything!).
