They are in PA, but as heads up, I checked with them on CVRs and they were way expensive, plus the shipping was also up there. There are other sources that seem more reasonable.
What are you trying to power or reduce the voltage to?
three six volt 1940 Ford gauges
Speedway motors carry a 12 to 6 volt 1 amp reducer called a "runtz"
I have used them before and they work real well. (one for each gauge)
they cost about 20 bucks each.
They also carry another reducer that will handle 3 gauges.
P.S. It can also correct a Amp gauge if you are running one.
