One thing I miss about having an electrical mfr. here in So Cal is the ability to just take a 45 minute drive and get oddball things tlike that.. Sierra Electric used to be in Gardena, CA till they got eaten up by P&S ... I once got a 22 gang Stainless switch plate next day from them. Quite handy
If you happen to live in the NYC Metro area, you might try the same thing with Leviton in Little Neck, NY or P&S in Syracuse, NY..
