just a thought.....working in a Jeep parts dept as i do, this 'may' be the situation. when a new model is introduced, such as the Rallye model, the 'kit' you mentioned is ONLY available as that....a KIT. if you need one piece of it to replace should it become damaged, you have to buy the entire KIT. i run into this all the time with truck running boards and other Mopar Accessorys. initially, they simply do not supply individual parts for each and every 'kit'. maybe, just maybe, you have to purchase the entire kit to get the lower front fascia.
just a few weeks ago, a body shop i deal with had called for the 'Rallye' name on the door of a Compass. no where in the EPC was it listed. i had to call Mopar and after several days, they called me back with a part number so that i could order it. they told me that this was part of the "Rallye Kit". your dealer may have to make that phone call to Mopar if there is no listing for the part you need.
if this hasn't been resolved, POSITIVELY, by Monday....i'll check when i'm at work and see what the EPC says. if no listing, i'll call Mopar to see what the availability is, OK?
