I could not find 202018 in either my '49 oi '51 parts books. However, as it turns out the Molding clips I pulled off this '51 Frazer hardtop rocker panels had a number 201 on the backside and it matches exactly a sample Restoration Specialities sent me. As for the outside door mouldings, I believe I found a macth with a 1946-48 Chrysler hood side panel moulding.
I would have preferred to go with "simple" push-in rocker panel moulding since the panels were replaced and last time I looked I did not have a drill bit that drills a square hole like on the original rockers and like the clips are made for; however I have a round drill bit and know how to use set screws. Some of this stuff you get into one must just ponder...why...why was it done that way. And we will eliminate the inside door mouldings studs/nuts since there is no reason to do it that way and no access anyway unless you pull all the door insides off.
