What do you think, is it worth trying? I noticed that the 7900 series has a lug width that is smaller than the GX-56's. Since they both use screws and not springbars I think the nylon strap would fit, and being non-tapering, it would not look too small for the King. If it is the other way around (7900 having a wider lug width) I don't think it would work. Of course I can just order the parts first and try them out, but local Casio supplier is a bit stingy about ordering spare parts. The fact that they are mainly importers and not really "Indonesian Casio branch" may have something to do with it. I might have to import the adaptor and extra 7900MS band so am trying to ask around first before jumping in. The look that I'm aiming for is similar to the GX-56 + Bell&Ross BR01 nylon band someone did previously.
