It'll fit, don't know why they had that on there Obviously the floorpans and strengthening underneath the cabs are quite different from a roofed escort, but that won't effect where you have to rivet the kit [or screw it]

If you're buying it off ESP, may be worth telling them when you ring in your order

By the way, see how much Ford do the kit for as I'll be VERY surprised if it's alot more expensive than the ESP stuff AND of course you'll have the manufacturers originals
