Sill Plate Rivets

[Unreal]

Greg,
Unless you didn't research very long, I doubt you can ever recover your research costs. For most of us, research is part of the hobby, and we freely share what we learn.

I just looked at the 6-7 original sill plates I have, and the rivets are different on them all. Some are flat, some are domed, and some have a flat outer ring with a slightly domed center. Guess it all depends on how the rivet tool hit the rivet.

Back to your question, I would think $ 3-4/set, including mailing cost, would be fair.
