Choke Thermal Vacuum Switch
Anyone know where I can find this part along with the vacuum ports and lines? I broke it and no stores seem to have it in stock; I doubt any junk yards will have any spare 70s-80s era GM's. It's all hondas and toyotas around here.

I have never heard of a thermal vacuum switch for the choke. Those are generally used for the distributor vacuum advance. You'll need to find a part from a donor car as those are not reproduced.

Yeah, this thing is attached to the air cleaner ( i think it may be called the MAP sensor but im not sure) one line goes to the TACS and the other two connect to the rear vacuum break of the carburetor and a source of manifold vacuum.

You could try high temp epoxy. Yah, I recognize that piece but don't think I have a spare. Pretty sure it was used till the end of Olds V8 production, so it should be at any yard that still has 80's cars.
