They started in CA - I found a reference as early as 1998 (on the H.A.M.B.)
I bought an electric wiper from them around that time. It did not fit a 1954 truck with original radio/speaker (no one sells one that works, but they said their's would work). They took it back (but, I had to pay shipping one-way - ugh).
I bought from them a few other times. Good prices and service.
