to my knowledge, besides tearing apart the interior, and a "cold" air inlet setup.. nothing. i did learn a year or so ago, that one of the previous owners, if more than one, put subframes on. i dont remember if welded or bolted.
which sent me on a quest to contact the person who apparently left some paperwork in the car, stuck behind the glove box. that mailing proved a waste of a stamp. almost. i do have the person's credit card number...
so i stuck it in my binder of car work, along with a written response from ford about what options et cetera was originally on the car..
question - what is the last day they make cars for any year model?
Every company does it differently I think. I was able to by a 2003 Tibby for my wife back in '01. :dunno:
You can contact FMC with your VIN though, and they should be able to tell you everyting about it. I did that with SLP for my Maro, and it was kinda cool.
