We know four-eyed Mustangs and Capris used 4656 and 4651 headlamps, but what about other four-eyed Foxes? Do they use the same 4656/4651 combination?

And then what about two-eyed Fairmont/Zephyr, Granada/non XR-7 Cougar, and Thunderbird/Cougar XR-7? Is it 6054 for all, or something different? Do any of those have four eyes and two eyes in the same model year? If so, which model/trim level had two eyes and which had four?

I know there are some F/Z and T/C experts in here!
