I need to know if there is a seal between the m/cyl and vacuum booster to seal vacuum on a 76 spider? Any help is much apprecieated.

Do you have a vaccum leak that produces a weasing sound coming from the firewall? Can't help you because I have a similar problem on a non-alfa.

No hissing from the firewall. I have an irradic idle concern from my Dellortos. It idles up when the brake is depressed and take a bit to come down. I don't know if there is supposed to be a seal between the master cylinder and the booster or not as mine was damaged in a fire when I got the car.

If the o-ring on the piston between the master cylinder and Booster was bad the Engine vacuum would suck up break fluid and smoke like a bad diesel when accelerating, It probably is a vacuum leak somewhere
