Elkman,
I have one bolt stop for an action I do not yet have any immediate plan for; I will be happy to mail it to you. I also have a sheet of high strength stainless in the correct thickness that I had planned to use for making a few bolt stops myself, but have not got around to (would be a hand file affair for me).
Please let me know if you would like to take a Crack at it. I do need the bolt stop back eventually.
