Need to find an AC/heater vacuum switch for my 1976. AC Delco part # 15-71518. Lots of folks on the internet say they have them, but when you call, no such luck. It's the vacuum diverter located on the back of the climate control levers. 1977 part will work.
All help appreciated.
Thanks

I know where there is a 73 but not sure if the controls are the same.

try auto zone

Anyone ever done internet business with Daves Discount Auto Parts in Indianapolis, IN?

..you might want to look at a "73",the vacuum valve is made of pot metal,not plastic,and it will last longer too.:beer:

I got mine out of a 73,and the vacuum valve is made of pot medal,not plastic.if your going to a junk yard,look for these cars with these controls: 73-77 Chevy Impala,Monte Carlo, Chevelle/Malibu and of course El Caminos.gool luck and have fun..:beer:

The 76-77 is a 9-port rectangular plastic one. Do you think the 73 metal one will interchange?

....No..you need the hose that connects to the metal one..

Not sure if you're still looking, but I may have a spare NOS vacuum switch coming in the mail here soon. I bought new control box, and guy had everything attached to it still!
