T86aa Parts?

Hi All, It's been awhile since I have posted. I am looking for a source to buy a specific part that fits into the T86 Shift Tower. There's a small, maybe 1/4", steel cap that holds in a cylindrical keeper that goes between the shift rails. The keeper is like a poppet ball, but more "Zeppelin" shaped. Does anyone know a source where I can get them, or even one?

Ha! I found one.
