Both vehicles have 6 1/2' round speakers, so some of them are interchangeable. However, those are the only set of speakers that are matched among the vehicles.
Both the front door speakers and the speakers in the rear are standard Ford 6"x8".
6.5
5x7 6x8
6 X 8
2 front door speakers 2 tweeters in front doors 2 rear door speakers
if i am not mistaken the front door speakers are 6 in a half inch and the back speakers are 6x8 inch speakers.
from80's to 98 its a 6x8 in front and back
It depends on whether or not the escort is a hatch back and how much you are willing to spend putting this stereo in it.
The stereo color coded wiring diagram on a 2008 Ford van is what shows you how to hook up a different stereo system in the vehicle if you choose to do that. The purpose of the diagram is so you hook the new stereo up correctly and all features and speakers work properly.

if it's an f-150 it a ford not a chevy so no a chevy motor will not fit in a ford without changing the entire drivetrain and computer .
just so you know when i put a new stereo in my aerostar i had to run new wires to the stereo speakers because the stock stereo had a common ground so one ground for two speakers i damn near fried the deck figuring that out hopefuly you wont.
