Do you have one of these? 66,67 skylark a/c mixer diaphram. If you are parting out an a/c car I would be glad to take the box as well as the diaphram. Thanks
You may be able to repair it. Source a vacuum union of the correct size, drill the hole out so one end can be slipped into the housing. Epoxy it into place with JB Weld. A little bit of scuffing and some semi-gloss black paint and it will look like new. Although not that particular part, I've repaired many vacuum actuators that way. Just a thought in case you can't find a replacement.
Please post back if you find the part or repair the old one. I've seen a few posts here just like yours for that same actuator. The broken off nipple seems to be common.
As already mentioned, Old Air Products has them. I bought a new one from them a few years ago and they told me it was the same diaphram as the one in the right side kick panel from a later a/c car. I'd have to look it up but I think I paid around $40 or more for mine so if your could find a used kick panel you'd probably get by cheaper.
