Just a suggestion......check with Tom Langdon (Langdon's Stovebolt) for his adaptor, linkage, Carter/Weber, and heat plate....also you may need an electric choke kit. Finding a matching Carter from AutoZone or for that matter any supplier may wind up being a shot in the dark.
I tried to find a rebuilt Rochester...Az's rebuilt was improperly reassembled and the choke circuit wouldn't work....went with Langdon's single Holley/Weber, adaptor, linkage, choke adaptor. It worked great right out of the box...made my own heat riser using manifold heat. For a dual carb setup Langdon can fix you up with a pair of matched carbs and hardware that will eliminate a lot of headaches.
