No brake booster. Car has manual brakes. The vacuum system for the wipers/headlights is partially there as well. No vacuum reservoir i can find.

This is the place I used. I had a 71 roadster. Didn't do a ton of work during my ownership but odds and ends, including headers, exhaust, carpet.

I think I miss that car. Maybe I have to get one back. I would like a restomod with a modern engine, brakes etc.

Vacuum reservoir is hidden in the frame, low in the front.
No vac wipers in a '76. Headlights and vent system only.

My recent experience wih the 65 Mustang led me to use any outfit with Mustang in their name only for information gathereing. It's very rare to find a retail outlet (Like Pelican, fo instance) that actually makes parts.

So get a price from one of these retailers then go to Summit Racing.......same part, less cost, AND they get it to ya quick. A big plus is their customer service is top notch. Their web site navigation is user friendly...the best I've ever seen and they got the stuff....most is in stock, with an occasional drop ship.

Not much in the way of Porsche parts available there.....which is a good thing for Pelican.....but heavy on American iron.

My vacuum reservoir is beside the brake master cylinder ,tucked under the fender. large basically rectangular metal box. 1972.
I believe basically the same 1968-1980 Early ones had 3 ports later only 2 (no vac to wiper door.
Looking at ebay prices from $10-250.
Also look at Willcox Corvette , lots of how to stuff under repair articles.
