WANTED: Slant six Holley 1 brl carb (Preferably 1920 model)

Hey guys, I have a 225 6 in my Valiant and I've had numerous issues with the carb since I bought the engine, but everything else operates smoothly, no mechanical problems at all. Anyway, this is my daily driver and if I were to rebuild my current carb I'd be without transportation for however long. I'm looking for a decently priced single barrel to throw on while I rebuild (or one I can rebuild while I nurse the current one). Any help would be greatl appreciated!
