Case Red Imp scales are made of bakelite with the carbon removed in order to add pigments (red). Otherwise, they would be black. The removal of the carbon content caused them to shrink and warp!
Soak them in 3M silicone, tighten the pins, sand the wedge flush with the scales. Then, take a hacksaw blade to the inside of the white wedge in order to make the blade fit. Soak them again in the silicone. If that does not work, get the scales replicated in something red. They need to be red! JMHO
