Anyone know the difference between the following two water pump pulleys?
C5AE-8509-B
C5OE-8509-A
Although the 1st one is a "Ford" part and the 2nd one is a "Fairlane" part, they are both listed as being suitable and used on '65 & '66 Mustangs. Anyone know if they were different in any way?
Thanks in advance.
