Hey i was wondering if a few of you guys with 75 vettes would help me out a little here. I need a few pictures of the vacuum lines around the carb to figure some things out on mine. So I am asking that if you get a chance can you pull the air cleaner off and take a picture from both sides and the front and back please? Thanks guys...

best thing you can do is to get the shop manual for it. they have the diagrams in them the way they should be routed.

I have an AIM and I have Haynesbut all my emmisions components were removed so it does not totally match up to what I have. But through lots of thought I think I finally figured it out today. Right now I have the large one on the back of the carb going to the brake booster, the small one down low on the back going down to the transmission, I have the vacuum advance in the front near the top, the pcv valve on the large port at the bottom front then going over to the driver side valve cover throught one of those pcv/breather hookups, I have the headlights run to the intake manifold but they still will not work I think its a problem up front with a bad hose but I will find that out tomorrow when I get a vacuum gauge. Right now the only things I am not sure of how to hook up and where to hook up are both on the passenger side of the carb.
The first one is toward the back and looks like it used to open and close the secondaries on the carb but I am not sure cause it looks like some linkage is missing. right now it has zero vacuum lines run to it.
The second is at the front of the carb on the passenger side it may be choke related but i am not sure it had one vacuum port on the front of it and ithas about a 3 inch hose on it running down to the bottom front right of the carb.
Also what gets hooked up to the port on the top back its small i think it may be for something emissions that i don't have
