I know this is an old post, but can anyone tell me where to find one of these YF Carter carbs. I've got a 235 out of a '55 bel air and I want to get rid of the Roch, but I want to stick with just one carb and not spend a fortune. I've read so many bad posts about the single H/W I think I want to stay away from that. This sounds like it would work but where do I find one?

I did see this (sorry, I can't find out how to add a clickable link, please copy and paste this if you wold?): http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Carburetor-United-Carb_3451097-P_26_R%7CGRPCARBAMS_1261785240___
it says its a "united" carb, but it does say its a "YF"
