The LeBaron GTS was essentially the same as the Dodge Lancer. These numbers may help, but none look in stock. The right side numbers are even, the left side are odd.

I show 4520731 as the LF door w/strip:

If the plastic T-shaped retainers have torn out of the rubber holes and rubber isn't too badly deteriorated, you may be able to use strong adhesive to reattach the retainers into the w/strip holes and re-attach it to the door.
If you can't find the factory body side moulding pieces, then you might consider generic wide black rubber moulding all around the car so that it all matches.
