1971 Challenger Convertible Tack Strip Hardware

What do the bolts that hold the rear convertible tack stripes down look like? Does anyone reproduce them. Look like 1/4 inch with large washers. My project has the strips but no bolts.

These are the ones that go in the curved side pieces with the large round hole.

I believe that Jules the Wiperman may have made a run of the rectangular washers at one time...

Thanks Guys,

That's what I needed to know.
