1974 302 Bronco Vacuum Diagram Needed

[rtremaine]

I've got a 74 with a 302 with a dual vacuum advance distributor, 2 bbl OE carb that I'm trying to put back to the original setup. It has a 2 port thermo vacuum switch and a 3 port switch, and egr valve, and auto trans. I've looked at several diagrams on this site but I haven't found any for this particular setup. Anyone have a factory diagram for this ? Thanks again !

74 2BBL 302 Original Vacuum Diagram

I just rebuilt my 74 302 with a 2BBL, I took pictures before disassembly and no longer have them. I would like to know how to run the vacuum lines as it was done originally but can't find any diagrams anywhere

Yes I saw that one, unfortunately the vacuum diagrams posted in that thread are for a 73 which is significantly different. thanks
