I swept for two MONTHS with only a broom and still haven't located that bugger, I assume it's critical to the mounting of the cartridge but wonder if I could just place another nut beneath both sides instead.
The nearest place for needles is about 28 miles away in Caldwell, Idaho, a place called A-Gem Electronic Supply agemsupply.com and that's no guarantee that they'll have it...it's a pretty nice store though-NOT a Radio Shack but a real electronics parts shop with real electronics pros and not some kid trying to pay for community college.
