Default Tripower carb inlet size

I can't believe I can't find the answer to this question anywhere so I'll give it a shot here. What size are the carb inlet fittings on a '64-5 tripower? I'm finally giving up on the stock fuel system and going custom, and I'm going to need -AN adapters. Thanks for the help.

Thanks b-man, I'd seen 5/16 NPT, 1/2-20, 5/8-18 and 5/8-20. It was starting to drive me nuts.
