You can make anything you want from the pats if you have enough time and money. The Sierra floor pan is longer than your escort so you will need to cut and shut it. This needs to be done properly of course for strength etc. I have done the conversion to my mk3 escort which is basically the same. Have a look at my build thread in my sig. there is plenty of other guys on here that have done the conversion too, there’s loads of threads with basically the instructions how to do it! Just have a look.
