It's the heater plastic thing ( manifold?)with the nipples that always break off. Once I know what it's called, then I can do a search. Thanks.

So, has someone repaired it, and what adhesive was used?
I have spare nipples.
You will need JB Weld “plastic weld” or “plastic binder”…..an acrylic like super glue may work too. If possible, I would recommend plastic weld, scuff both surfaces and clean with rubbing alcohol
 
I have used this rack (found in hobby and hardware stores) to fix many things. On a fix like that, I would consider drilling it out and glueing in a piece of hobby brass tube.

thanks for this! I didn't even know such a source existed. Please share which specific store this is. I don't think I've ever seen this at Ace Hardware of Hobby Lobby or Michael's, but I'll need to look again. The most I've seen without going full length plumbing is at the Auto Parts store on the small spinning rack where they may have 3 sizes of short tubing. The small pieces of sheet are also very cool and I imagine I'd make use of those for several things. I know you can also buy some stuff like this from McMaster Carr online, but there's something to be said for holding the piece in your hand and seeing it under normal lighting before buying.
 
I had a spare vacuum switch, and I opened it up since it was in bad shape, and the nipples have a larger inner diameter than the holes on the flip side of the nipples. So, if I drill the holes out to put in the brass tubes, I wonder what that would do to the function of the switch. Plus, if I go with very small tubes to keep the orifices the same size, then the vacuum hoses won't fit.
And I went on ebay, and the only ones that were listed were not right for my car.

Small hobby shops, though some Ace and HL say they have them . The tubes are graduated and fit tightly with each other . I used round tubes to locate centers of a pumpkin's pinion and output shafts and install a similar but larger diff. Their fit is very tight.

Before you work on the nipples make sure the buttons do what they’re supposed to do. The fiber wafers inside wear out and doesn’t shift the valve right. There is a guy in Texas that rebuilds these switches, but I think you could fabricate the wafers out of plastic. I bought a new complete switch from Joe Suchy.

My experience is the reproductions for 66/67 AC cars don’t function smoothly at all. I have to pull the last button out before pushing in another one. Fortunately I have a good original I’m going to put back in it sometime.

Everything was working fine when I took the car apart. But, I am curious what Joe Suchy charged for one, if you're ok with mentioning it.
