I'm looking for a Bendix carb with Bendix part number 13479 stamped on the round raised section on top of the carb. It will also have a letter A-E and probably the H-D part number as well. Mainly looking for that Bendix part number and a high a letter as possible. I know any Bendix would work but this part number was used '73 and earlier and my bike is a '73 FX and wanting to do a correct resto. Thanks much.
