I still suggest you consider your resason for the dual carbs, looks or ease of set up. I did mine for looks only and decided on the period correct Carters. It has been a a lot of work getting them set but now that I have them there everything is good. After all, that is why I started this whole project to begin with, to put it together myself.
Just my reasoning.

If you never tell a lie, you never need to remember what you said.
