CB350 Carburetor Main Jet Holder

As a novice to motorcycle building, I messed up. I was rebuilding the carburetor on my 1971 Honda CB350 and broke the "legs" off of the primary main jet holder and cannot find a new one anywhere! Any tips? I can't find one in a junkyard anywhere... Borrowed this photo from google. (see attached)

It will still work with at least one leg still there. If both are broken off, it's no good. I believe there is a Keyster set that includes these emulsion tubes. A bit pricey, about $60, IIRC.

Yeah, I hope there's still at least one leg on there... I saw the Keyster kit, but it is a bit pricey. If I'm paying $50 per carb, I may as well buy some Mikunis... I've been emailing a few people from Minnesota looking for one. I'll probably also take a trip to a big motorcycle salvage yard about 45 miles from me. I'm just afraid that this model will be stripped. Thanks for your help.
