Maybe I misunderstood. If this is a package for folks with GGTS that does not have brass contacts, then no. If this is a general package for replacement of all brass contacts, then yes.
I guess I'm just saying that they should be available at some point.

The end of one side is very close to the oring and will eventually be buffed down too close to use. Why not make that end longer like the other end so the part will have a longer lifespan.
