Up for sale is a new old stock turn signal that is correct for 1963-1964 F-100 and F-250 pickup (except 4x4). It is new original Ford and super nice! I don't believe the box is the one it came in because someone hand wrote the number on the lid? You're not going to install the box on the truck so I guess it doesn't matter anyway. Very hard to find! Part number C3TZ-13341-B. Send back if you are not satisfied.
Thanks for looking and please be sure to check out my other FORD parts!
