Hello. Just got into a corvette parts stash. Lots of 60's parts including 6 pair of fuelie heads and 2-L30 327's. Wow, hog heaven. Also came up with what looks to be a 1957 plymouth poly dual 4 intake complete with carbs,feed tubes and linkages. Numbers are- 1822004 , date code L 11 7, Front carb 2631S, Rear carb 2632SA. I believe this is the sleeper in the batch and could use help identifying if all original. Wouldn't chase away ridiculously high offers to buy either. Thanks for the help and stay healthy. See pictures.
