Default 73 big block manifold //

I am replacing my 73 454's manifold with a factory original and the correct quadrabog. I got the manifold and the carb and the carb bolts but nothing else. I dont plan on installing the air pump and injector equiptment but do plan on getting everything else correct. I have not found any good pictures of the way it came from the factory. I know there is a vacum port that goes behind the carb but no idea what it looks like. Also what goes in front of the carb on the flat surface with the two holes? I think an egr valve ? Also I assume the left valve cover hooks to the air cleaner housing and the right valve cover pcv valve to the carb??? Does anyone have any pictures of the manifold and all the hookups with the aircleaner removed ?? Also what holds the throttle cable in place ? Any and all help is appreciated. Thanks Desprite in Arizona !!!

Get the factory assembly manual. GM used it to build the car. It will have the info.

steve, I have the assemby manual also, not a single picture of the egr valve. The closest it comes is a disgram of the hoses that attach to it. If you find something let me kow what page so I can check my manual. Do you have a 73 bb ? Thanks Jackn
