I like my local BMW dealer for airhead parts.
Hucky's kit for later 32mm carbs including diaphragms is $11.50 less than getting the parts individually from BMW. $83.40 versus $71.90. The savings to me is inconsequential since chances are you don't need some of those parts anyway. The diaphragms for instance, that's a big part of the kit that you probably don't need plus the diaphragms themselves might be some of those that are too thick and effect jetting.
Another Hucky's kit that I checked into was no savings over getting the parts individually at a dealership at all.
