4 brl carb for 66 cuda

I have an NOS Carter AFB that is correct for a 1967 Barracuda Formula S that I would let go for $300 plus shipping. The only blemish I can find is that some of the cadmium plating on a couple of the linkage wires on one side have gotten chalky looking. Other that that, it looks and i guess is brand spanking new. Can't see why it wouldn't work like a brand new one.
