I don't think I have one of those '72-only parts here, but my advise 
would be to leave it out of the circuit. On FI '72s that valve served 
to allow the vacuum advance to work only in top gear (4th for MT, 3rd 
for AT.) On my FI MT '72 I ran the vacuum line directly from the 
distributor to the Intake air distributor. It worked perfectly that 
way.

In the lower gears you seldom get enough vacuum from that port to 
activate the vacuum advance anyway, so that valve is part of a pretty 
pointless system.

If you really want one, I'll look thru my stuff more carefully or 
Dennis might have one from one of his '72 engines. Nevertheless, I 
think you're really better off without it.
