Wayne You are looking for the 0190/4, which is a 661 in plastic, right? Those are still around here in Denver. Like $4.00 for a pair. Don't you need other small stuff to be mailed down in same thin envelope? For $4.00 US mail you can get a lot of small parts sent at once. Joe Hughes Denver, CO rotab@msn.com<mailto:rotab@msn.com>
