CARB number help
If your carb is truely a '67 Carter BBD for a 273 with a manual transmission the number on the tag would have been 4113SA. Although, 99.9% of the rebuild kits I have seen fit pretty much all non-emission style Carter BBD 2 barrel carbs. That's the problem with parts store help now-a-days, they are only book smart meaning they can't do anything unless it is listed in the book.
Use the 4113SA number and the kit you get will work.
