67 a/c truck water shut off valve ???
 

did 67 a/c trucks not have this valve from the factory? i have pics of 2 67's that dont have them. the lat pic shows it on the pass inner fender on a later year truck.

My '67 GMC does not have the water valve, nor have I ever seen that water valve on any other '67. I think it was used on '71 and '72.

i wonder if there is a difference in how cold the a/c blows with and without this valve.

I have one in my 72'. I replaced it when something happened with the AC/Heat on the advice from this forum... cant remember what it was, unfortunately. I had to go to Napa to find one, I believe.

The assembly manual does not show a water cut-off valve on the 67s. It does show them starting in 1968. 68s and 69s used a valve that was not screwed to the inner fender. I believe that the valve that is screws to the inner fender started in 70.
