Acrylic Targa Top Repair

[ScottZ95ZR1]

I recently received the top pictured below. As you can see, the two black molding pieces on the drivers side of the frame are missing.
I don't know what the correct name for these pieces are and have had no luck locating them on MidAmerica or Ecklers websites.

I'd certainly appreciate any help in finding a source to obtain these critters -- whatever they're called.
