I checked them out thanks the photos of befor and after where amazing I think we found a winner. thanks again.
Do you know of a way to find out what the patr numbers on these carbs would have been from Mopar Direct? I have found sevral sites stating they where a dealer item but cant find any old catalogs or info from Mopar Direct.
