If you can use a top quality (read: thicker, open-backed,
somewhat more expensive) 6.0mm bezel cup, my store,
Metalliferous, stocks them. E-mail me or call me at 888-944-0909
Monday through Friday. The store is open from 8:30 am till 6:00
pm, but I don’t get in until after 10 am. (Hey, no banker’s
hours jokes. I’m usually there until 7 or 8.)
To be honest, if I could remember the prices, I’d quote them
here, but I’m doing this from home.
I hope this helps.
