Need help identifying 2 engine bay items

[Damomma]

I'm finally completing my very lengthy rebuild of my 78 911 and have found pretty much all of the parts. Unmarked hoses have been fairly difficult but it's done and ready to go back in the car except for 2 small things. It's funny that the two things I can't find are items that shouldn't be on a sports car in the first place ie the cruise control and the AC. But everything worked when I took it apart and I'd like to get back there.

1. I can't figure out what connects to the cast threaded fitting that comes out of the top of the cruise control canister just aft of the vacuum line nipple.

2. My AC compressor platform is missing some kind of support bracket that connects from the forward part of the platform to somwhere on the engine near the 4th cylinder. It's possible there is no such thing but the platform is not very rigid.

Any help is appreciated,
Jamie
