Del Val Miata Club

I'm looking for a "boot cover" (covers the convertible top when it is down) for a 1991  (NA). I don't care about the condition of the fabric, color, etc, I just want the piece that goes under the rail to clip it in place. It is needed for a custom top.

Thanks

i am missing one clip for my boot. if you describe the part on google it will give you the right name for the part . they are still made and are not expensive
