Lincoln LS Rocker Panel Moulding Retainer Push Washers

[LincolnSedan]

Am looking for the part numbers, some sort of link to the push washers for the LS rocker panel mouldings behind the Passanger (or drivers) side front wheel wells. There appears to be 2 different sizes that are very specific to the hole in the body, head to retain the trim piece. One goes on the lip at the very end of the plastic wheel well housing (back wheel well cover). The other goes on the underside of the rocker, looks like it has a phillips head. The trim is making noise, very annoying. Do not want to drill holes in body, use screws if possible. May upload pix if time, I have a number of fasteners for this car cowl other push retainers, none of these. Seems like ebay would be one place, cannot find an exploded body diagram online.

Thanks.

Last I knew, Napa had some that would work. A Ford dealer might still have them too.
