65 Buick Special 2 port vacuum switch

I have a 65 buick special thats in need of a two port vacuum switch that is located on the pass side of the firewall, near the fan motor. I believe it controls the vent. Im replacing the heater core, so a quick find would be great, so I can put her back together. Any suggestion to where I could locate one or something I could use in place would be appreciated. Thanks

 

Hi,
AC car / non AC car, I have an AC car here but can't find the part you describe.

thanks Bruce

 

a/c car, measures about 4" in diameter, white in color, two vacuum hoses, one in center, another just above it, looking at firewall its located just right of heater fan, beside where vacuum hoses come thru firewall. Has ac delco remy cast in it, no part number.

 

Heres a pic:

 

Hi , the car I have here has one on it I'll check it tonight

thanks Bruce

 

Hi, sorry the upper vacuum line port on the one I have is broken off.

Any idea for replacement?

 

Well, Ive looked thru various websites, and havent had much luck finding anything. My part doesnt have a number on it, which adds to the problem. Ive tried looking at part illustrations but havent had much luck there either. So, my needs would be:
1. A replacement NOS or a used one in working condition
2. A part number so that I could conduct a better search, and or cross reference this part to other applications
My final option would be to have a new housing machined to replace the broke plastic.

Check these guys I think they have them under 66-67 gto

 

Thanks for the replies.

I found several on E-bay yesterday using the term 'dual port vacuum actuator'.
