Gentleman, got the heater core job done on my '73 today. Now, where do all these vacuum lines under the hood plumb to? The P.O. had them all disconnected. There are two connections in the middle of the firewall top center - I have no idea where they go. I suppose the factory shop manual would be good, but anyone have a source for them other than ebay?
If your car has factory air, one goes to the heater valve on the cowl & the other goes on the vaccum cannister on the pass. side inner apron. Hope this helps.
