I was just wondering where you plug the vacuum hose into the carb (from the distributor) . My first guess would be the tube at the top of the carb in the first pic (if thats not what is that?). And why there is a screw blocking a hole that leads to the passenger primary venturi.

the hole that is blocked by the screw in plug is where the distributor vacuum goes. you'll need to buy a fitting to replace that plug, just make sure you get the right thread pitch, IIRC it is NOT a pipe thread.

Thanks for the reply. I figured that was the port for the vacuum, but I didnt no why ford manufactured a removable fitting. I visited 4 places this morning to look for fittings, but the tubes were too big for the hose. Im gonna call pony carbs and see if they have replacements. If not I might see if I can get someone to make one for me...
