- 1971 Mustang Mach 1: 351 C (modified), FMX trans (modified), 9" 3:25 traction lock rear gear. I have owned this car 44 years, since I was 17.
I am having difficulty finding the correct PS pump pulley. Most stuff is up-to 1970. Furthermore, the sizes vary widely. I have a 351C with A/C. Can anyone advise what size pulley I should aim for or a part number. And does the diameter size matter so much and if possible to what varying degree or range of size measure is okay to use. I feel like I am over-analyzing this but the more I research the more confused I am getting.
