Hi Bill - I found more info on the adapter, and we can talk about it when I find the last part number. I want a set of the flanges now. You also have a pair of the mounting flanges that work with the stock exhaust manifold - as in several of your pictures of the intake on the kitchen table. Can you do the carb mount flange to fit the A-B carb mount? I will call you in a few days, regards, Steve
