Stop in for a cup of coffee
Those are the guys I was telling you about before. They'ld be sitting on these old carbs like a Chrysler reverse idle Holley and finally just make it into a modification project since they didn't know what else to do with 'em. Baldwin has website so you can send him an e-mail. He does a lot of performance stuff but that doesn't mean he won't have factory carb in the collection.

The other guys there prob don't have a website. I'd have to post a want ad.
