I purchased my NOS Rocker Panel Moldings from my Ford Parts Counter three decades ago. They of course were not in stock, so they had to be ordered in. When they arrived, interestingly, they were in two different types of packaging. One was in a long brown paper "envelope" with the Ford Part Number printed in black ink on both sides of the outside, and brown paper with a "block" FoMoCo on the inside (first picture). The other was in a totally different type of envelope ; the "back" side was a piece of brown paper on one side with the Ford Part Number printed in blue ink, the other side also being brown, but with the addition of the Ford Oval and the printing of "Service Parts printed in USA", and shrink wrapped in clear plastic on the front side (picture 2). On both, the front clip was installed in the molding (picture 3). Luckily, both had on the inside, unopened "bags" of the "attaching parts", SUBK - 1622 - K (several pictures showing bag and contents).
I have heard of some "NOS" moldings that came with no hardware, much less an unopened bag of it, which makes one wonder if they were truly NOS.
Also of interest is the number of retainers that came with each Kit ; both had 6. While this would cover most cases, it does not cover mine. My 67 Convertible was built January 31, 1967 in Dearborn, and came from the Factory with 7 retainers on both sides. This will of course result in my using the 6 NOS retainers and one of my originals on each side.
As far as having your old moldings repaired or trying to find new NOS ones, you may want to look at having what you have restored. I say this based on the most recent ones I saw listed (I can't remember if on Ebay or one of the Forum's "Parts for Sale" listings, but it was for $600 . While I also can't remember whether it noted "each" or "per pair", not cheap in either case. One would think that you could have them straightened and re-anodized for about half of that.
Hope this helps.
