ISO '74 472 parts and info
Got a 74 Deville with 472 looking for an EGR block off plate, and the vacuum valve that goes between the EGR vavle and carb on the intake manifold that supplies the A/C controls with vacuum. Also if anyone has the diagram for all the vacuum lines in the engine bay I would much like a copy of that. Bought a factory repair manual off line and it doesn't give a schematic of the vacuum lines. Found one on here for a 70 but once I saved it to my computer and zoomed in I couldnt read the text anymore to see what was what. Any info would be much appreciated.

Re: ISO '74 472 parts and info
The 1974 shop manual that i have has a fold-out diagram in color. When I'm at my shop I can post a photo.
I hope to be there somewhere this week.
