I still am not sure if anyone has seen this stabilizer style before. I managed to get the stab legs out of the one shift key I removed but they had clearly been epoxied/glued in. I just wiggled on them until they came out.
They're definitely epoxied/glued in. I didn't poke around the stabilizers (honestly, mine feel too solid... I'm afraid they'll snap), but I did some work on the wire and the clips holding it down. The wire can be removed by guiding it sideways through the clips, and the wireclips come on and off pretty easily once the wire is out.
I think the plate holes that the stabilizers glide through are too small for any of the currently on the market stabilizers...
Stupid question, but is there something that dissolve epoxy without dissolving PBT, assuming that is epoxy (it's like an orange color, but I know that can be anything)?
