Maybe they are all the same, but, the online store makes it sound like they are all different brands and manufactures? AcMango, KIPA, EVERESTWAY, ALAVENTE, A-Premium, Autodevil, LDCRE, ZDDK, cwcyer, etc.
Why doesn't one of these brands/manufactures make a carburetor to fit a two-barrel F-engine (F / F.5-type intake manifold, and matching air cleaner assembly)?
They are misleading people by claiming that it fits a '69 to '87, when it only works with a non-USA 2F, or a smogged-2F with a special spacer installed on top of the air-horn, or by taking the original carb apart and swapping-in the EGR inlet part, and, by installing a plug for the fuel tank return line. Depending on your model, you might need to source a cable-stop for the choke. And, who cares that it lines up with the studs on the F-type ('69 to '74) intake manifold, when it has no throttle lever for the accelerator cable, or at least a generic air filter sandwiched between a couple pieces of sheet metal (like a Weber)? It should be advertized as, "Fits a '75 to '87 non-smog Land Cruisers"
