71 Dart Vinyl Top Trim Fasteners

I removed the vinyl top from my Dart to do some repair work and get ready for paint. I will be installing a new top after paint.
My question is the fasteners that mount the trim pieces. I can find the clips but not the screws shown in the pics.
What are you guys using for these? Are you replacing the screws with clips or?
I can clean up the screws, I'm more concerned with the plastic washer.
Any help would be greatly appreciated!
Thanks.
