Eyepiece end caps

I'm looking for a source for 1 1/4" end caps.
I really don't like the rubber ones with the nipple, though. With these the eyepiece doesn't stand up with the cap on. Seems all the stores are only carrying this rubber nipple kind.
Any sources on the "old school" style?

Thanks all.
I had looked at Scopestuff, but did't see them at first.
