body side moldings

Does anyone know a source for the original style body side moldings. I have not seen them reproduced, but i remember when i was younger you could buy the stainless trim to fit style moldings that were similar. You trimmed the stainless then the insert slid inside and you finished it off with caps. I saw some brand new ones on a car at a show this weekend, but the guy did not want to share where he got them. anyone know?
