These clips are original MoPar NOS clips used by on all 1949 Dodge Rocker Panel Moldings.
There are reproduction replacements being produced today. I tried to price these less to liquidate.
This clip is MoPar part #1256009
I’m not sure how many clips were used to hold on the Rocker Panel Molding, which is why they’re for sale individually and not as a set.
For those who are unaware, NOS means New Old Stock. That is a part made by MoPar years ago, correct for the years stated but never installed on a vehicle.
