My 67's A/C unit has been removed over the years by less than qualified mechanics. I have most of the parts but I need a good tech book that covers the install/repair of 67 camaros A/C units. Any help out there. My car came with factory A/C.

As for '67 A/C, the assembly manual is definitely your best bet. All vacuum line and wiring schematics are shown. Of note, the '67 A/C system suffered from too much reliance upon a vacuum switch at the A/C / heater control panel. This thing apparently required constant replacement of a plastic cap which, in turn, required removal of a whole bunch of other stuff (you know what I mean). I chose to install the '68 version factory A/C system in my '67 following the assembly manual for that year for A/C only. The vacuum and A/C electrical systems seem to be a little more refined a'la '68. The wiring harness repro's for '68 cars include the ambient switch circuit and a couple of other quirks that can either be ignored or made to disappear (relay on top of evaporator box is different, etc.). One word of warning on '67-'68 a/c...remember how impossible a clean replacement of the blower motor is without the right fender being gone? Same thing is more or less true of the vacuum tank under the left fender. Get a good one and test it! Same for plenum valve and right side kick panel vacuum pots. Ain't this fun?
