Well, the bad news is that the pan is a service replacement for 67-68 Mistang, not a 64-66. Part number C5ZZ-6511135-A is for a 64-66, p/n C5ZZ-6511135-C is for 67-68, per Ford Car Parts Body Section 100 page 12. I would have thought that a C7ZZ- would be for 67-68 but "who knows what evil lurks in the minds of Ford". Sorry Lamont.
