I was just wondering if anyone out there has explored the possibility of duplicating the GE Elec Trak seat backs? The cushion shouldn't be a big problem for the right person with an industrial sewing machine and access to the correct material. That funny little forearm shaped backrest with the stamped logo is the problem. Does anyone have any contacts to the original vendor? I'll bet that Harold Z. and others could sell some of these if they were available.
