My 72 wagon uses the same turn signal as a Mustang. The Ford number for a 71-72 Pinto is D2ZZ-13341A which is interchangeabl e with several other Ford cars. When my turn signal finally died, my mechanic called National Parts Depot, among other suppliers, and asked for a Pinto turn signal unit. Of course they just laughed. I gave him the original part number and told him to ask for a 71-72 Mustang with-out tilt steering wheel turn signal and there was no problem finding a new part.
