Those carbs are made in Argentina by an outfit called CARESA; their site is
here. Daytona brings 'em in and marks 'em (way!) up. Fine, we have capitalism; that's how things work, but at the price they charge I don't consider this a cost-effective option. Yes, the external adjustability is nifty, but overall this is a copy of a
very primitive carburetor, with none of the many great engineering advances made in carburetion since about 1960. Add that to the basic fumbles in in the design (vertical bowl gasket and mixture adjustment seal below fuel level = leaks waiting to happen; side-hung float = tendency to stall in hard cornering) and the hassle of cobbling up choke, throttle, and kickdown linkages because these carbs were not made for this application, and the lack of provisions for various vacuum hookups on a '75 car that are well worth preserving…I just really think this isn't the optimal way to go. Not with NOS 1945s regularly going by on eBay.
At $100 or $150, the Argentinian carb would be an attractive option, because the lower price would offset some of the hassle and cobble-up.
