I just had to re build a sgl barrel carb for my wifes 67 F100. We found that NAPA had the best price on the kit and it only took 1 day to get it. The nice part is that it was only $20.00.

Also if you search a carb rebuild kit online you will see the part the other guys are speaking of. It kind of sticks out since it is the only part with a rod on it.
