In the process of switching from a edelbrock to a rochester quadrajet. The qj has a lot of fittings coming out of the carb. Which ones are needed? The egr was removed from the previous owner. I think I counted 6 on the front of the carb and 3 on the back. The back side has one near the top, middle which I believe goes to the brake booster and is tapped. And one at the base. The front has one on a angle and is 3/8. A tee that goes to the choke? And is opened. One on the bottom right but is not in the bottom plate. One to the left of that and is in the bottom plate. Another 3/8 dead Center below fuel inlet. And one more on the bottom left. Any help would be appreciated. Thanks rich

 

possibly the top front angled passenger-side 3/8" port is for air cleaner vacuum line, to close the snorkel flaps during cold operation. That one you can cap with rubber plug for now as you one by one decipher the rest.
