Your speakers are 6"X8". All four are that size and in each door.
I replaced mine with 5X7 JBLs in the front and 6½" Kenwoods in the rear.
You may want to consider putting a size other than 6X8 in the back doors as I did because for some stupid reason Ford didn't line the rear grill up with the speakers! The grills on the rear doors are horizontal, but the speaker is mounted in the door at about a 45º angle. What this means is a 5X7, or 6X8 speaker would be half covered up by the door panel!
That is the reason I put a set of 6½s in the rear openings toward the bottom of the 6x8 hole. This lines the speaker up pretty well with the factory grill. I still need to get my ass to work making a panel to cover the rest of that 6x8 opening though. LOL
