I recently bought a 1951 8n for a future project and the brass tag with the carb number is pretty beat up and the only numbers that are legible are the last two digits 39. I looked on a website that had every MS carb number for Ford but did not see one ending in 39. I think the kit for the TSX-241 will work. My 49 uses that one and the carburetors appear almost identical. The only difference I can see is the '49 has a tiny drain plug on bowl next to the main needle. Any thoughts?
