Anyone have the hardware from a 1970s-80s soft top?

I'm looking for the small plastic parts that go on the ends of the door
frame bars for my `79 CJ-5. There's a small sleeve that goes on the
rear end of the bar across the top of the door to keep it from
slopping around in the middle topbow, and a tophat-shaped piece
that holds the top of the upright bar at the rear of the door opening.

It looks like this is the original hardware, it might be Witco for all I
know.
