69 vacuum operating heat control valve with A/C

[Elefuntman]

Hello! I have a 69 c10 and I'm looking to get everything back to original as possible. The truck has factory A/C, and I need to install the original 69 vacuum operated control Valve. For 69 this doesn't screw to the fender like the later one. Can someone post pics on where the best place to put it is? Just doesn't seem to lay in there comfortably with the right angle! Also which end goes where. Thanks !
