Hey fritz, when I went through mine and cleaned them up, I didn;t use any parts, even the old bowl gaskets sealed back up. But if you are not going to split the carbs, you may get by with just a set of bowl gaskets from redeye,

If you haven't done it yet, clean your bench off and watch the youtube d ray videos that dan7uk posted the link to, everything you need to know is there.
While you are in the area, I wonder about the condition of your vacuum hoses and caps,, have you replaced those parts?
