F600 headlights

Hello all, looking for some more help on my build. I’m putting all the electrical back in my F600 and I have a question. I’m having trouble finding new headlights, they measure 5-1/4 across the face but everything I se eonline says 5-3/4 or 7?? I know 7” isn’t right but is 5-34 the correct size to replace the high and low on each side?

thanks!

1957 have single round headlamps, 1958/60 have dual round headlamps (low beam bulb different than high beam bulb).

All 1956/79 cars/trucks use the same round 12V seal beam headlamp bulbs.

Last year/vehicles with single round headlamps: 1978 F100/350 Customs & Econolines, 1978 Mustang II; 1979 Thunderbird.

Last year/vehicles with dual round headlamps: 1978 LTD (not an LTD II).
