redsplitwindow

Working on my buddies Original A/C Split Window.
The enclosed photo attaches to top of heater box and
Has 3 ports but only 2 vacuum lines.
You can hear the Vacuum leak.
Is this an original part or ............
Are the two vacuum lines correct?
the piece has a piece on the end that comes out and and pushes a metal arm.
Everything works but noisy and want it to be correct when we out it back together.
Any help or photos would be great.
We looked up the part by two different vendors and the reproduction part looks totally different
Thanks

You are working in an arcane aspect of these cars; less than 250 63s with A/C were built, your friend is a lucky man..

He absolutely needs to get a 1963 Assembly Instruction Manual from Wilcox Corvettes or the NCRS as there are a TON of A/C-specific, 63-only things on these rare cars that you'll run across and the A/C option is covered in that document..

I've found that Long Island Corvettes has the best repro stuff for the '63, maybe you could post a pic of the repro part and I can look at the AIM again.

One vacuum source, and two vacuum auxiliary connections.: One to STV valve and one to vacuum switch on top of heater box for the hot water valve to heater core.

I was thinking it was this "T" connector:

Ya we’re both aware of how rare this Coupe is.
Need to find out if this vacuum block is original and where the lines go.
Will check LI Corvette
Stay tuned I will keep you posted
Thanks

This is a 63 inner box.

65 Pro Vette

The 63 corvette has a unique inner box it’s one of the easy ways to determine a real air condition 63. And the vacuum switch is brass as pictured above.
