I am looking for a source for a rebuilt zenith 228 carb for a 1957 gmc 270. Does anyone make a rebuilt or remanufactured version of this carb? I am looking for one with a #3 base (the larger size) and a vacuum port on the lower throttle body section. preferrably with adjustable main jet but originals would not have this option from what I can find out

I have read articles that these were being remanufactured but havent had any luck actually finding one...any help would be appreciated
