Bob the Mannel book said that the only 68 Ford using a fan clutch was the 68 Cougar and it used a E-C6OE-A clutch. I guess he was not thinking of the Shelby's. I thought it was odd that in the Mannel book under 67 it said that the Mustang and Cougar used a E-C7ZE-B then in 68 a E-C6OE-A was used. I do not know if I will ever find a C8ZX-A, are there any good substitutes? I PMed you about the Air cleaner.
