I wasn't sure if I should ask here or under "cooling" but my search efforts found a few related threads here, so here I am.

If anyone knows where to find a replacement for the manual "HEATER A/C VACUUM VALVE" (if that is even what it is called), I would really like to know.

Mine broke a long time ago and I have not been able to find a replacement. I'm considering bypassing it and routing the vacuum so that it is always in the "Vent" setting. I've even considered using a fish tank air hose manifold, with a bunch of valves in it, so that I could switch between vent and defrost. But I REALLY don't want to add a rig like that to my car.

So please, if you know where to find the correct "HEATER A/C VACUUM VALVE" for an '82 Camaro (or anything even close), please speak up.

Thanks.
