I think the carburetors were identical from 1947 to 1953. One barrel Rochester. I will check and see if I have one, today. If I do, it will be in very good condition. I have six or seven. Just need to check the parts book. Hold off on buying one through Ebay. There is one listed for $450.00 and it is polished to gorgeous. I will be in the garage today, and will let you know by tomorrow morning if I have one. If I do have one, I will ask for a very lot less. My spouse wants the parts load reduced in the garage. I do not have a spacer for underneath it.
