1982 Lean Burn Carb ID

There will be a stamping on the body of the carb and those would also have the original Mopar PN (7 digit) and a R number which would be the Holley number which would be the carb number any parts store would want to help IF the carb and get the right kit.
I've had good luck the last few years finding carb kits cheap on ebay, but 2 things... You have to be willing to look past the first page of listings for anything there (prices are wild, I've found the same thing range greatly /don't necessarily but the first of any item you see) and. Look elsewhere for part numbers first so you can narrow down your search. Look at rock auto (also a great place to buy) and your pars store online catalogs and get the part number, often ebay has a part number interchange built in, you put in your part number and it will bring up equivalent pats from other brands, and will often have a list of vehicles the parts on that listing will fit.
I saw somewhere you are looking into a super 6 swap, do yourself a huge favor and look into a lean burn-ectomy at the same time. LOTS of talk about that here if you search...
