Looking through my notes from last year, not sure if this is helpful to any owners but the shop that fabricated many WCC interiors is located In Windsor Ontario. I stopped in for a visit in early 2011, not even sure they are still around. They explained that they did the stitching and fabb'd all the parts for the WCC interiors, they have no material in stock, they may be able to help with convt tops too ???
