69 Barracuda Sport Package Sill Molding

The end metal clips you can probably find something for another make vehicle that will work. Try AuVeco clips and fasteners. They may have something close.

Having these made from stainless steel would be much better than the anodized aluminum.
The metal clips look easy enough to, again, have scanned in like the plastic and then just laser cut out of a stainless steel sheets so rust isn’t a problem. While I don’t have the capacity for that where I am currently, I have tons of friends with tons of friends I’m sure I can find someone easily, I’d be glad to do the work to have all this stuff repoped and then sell it back off at slightly above cost.
