He sent me the pictures, I’d guess it to be about 6ft and 2 inch across. Like the normal trim, rolled edges in, just bigger. It was anodized aluminum if that helps?
Well, if you're able to reproduce them, I'd be interested. I went back thru the moldings that were in the car when I got it (stolen, stripped and various trash/ parts piled in it). I pulled one out, like I had before, held it up to the bottom and said yep, this is it (again no clips at all). I then pulled out the other one, it was longer, so it's from a Valiant or the Dart/Dusters that look the same but are longer. So unless I misplaced one somewhere else, I only have one side. So I hope you can re-pop them, or I may try the Classic Industries dart/duster repops and have them cut down and the edge rolled just right. Other choice is to weld up the holes and not worry about it for me, but I was liking the fact that not a lot of other's had the Sport Package, so no sill molding. Also mine is going to have a NOS clock that was converted to quartz movement instead of a tach or "performance indicator". @moparmat2000 has been fixing me up with some nice other mods, like the dual dash speaker mount and a custom console wiring harness that will have LED lights in a couple of discreet places to light up the areas better. Just a few discrete mods, since I was shooting for that "factory look".
