I have a 1980 Pinto Squire wagon that was made in September of 1979 and I need a NEW turn signal switch that mounds on the steering column and has the four way flasher switch incorporated. I bought a new switch with the Mfg. Part No: REPF505802 and it does not fit my 1980 Pinto. What switch do I need and what is the Ford Part number and where can I order this NEW switch?
