Sorry John, I haven't had much time to work on this subject but here's the place that would either have them or be able to make them. Granted they sell in larger quanties than 1 but then you can be the source. I know I'll buy 3 from ya right now.
I got 20 for the XT6 from them for $28 shipped to my door btw. You'll want to get the alt number off your alt before calling as I'd guess they'd need that.
