When I ran N/A I used the Autolite 764's. They are stock replacements and work great.

Anyone know if they're any NGK's, or any others that will work? I need to do an exchange and I'd like to exchange for something they have just in case they don't have the Autolite 764's.

The equivalent is Motorcraft 32c's i beleive.

I would hold out for the Autolite/motorcraft plugs. They seems to work best on our 5.0's

Would anybody happen to know the part number for the motorcrafts plugs for a 93 cobra? I plan on changing them soon, just don't want to go pull one out at the moment.
