K1 to M6 Adapter

Does anyone know where I could find a K1 to M6 connector adapter or how I could make one myself? Or maybe even a M6 to K1 adapter if either exists. I would prefer the K1 to M6. I have a headset that I need to use in two different radios (Motorola CP185 and a TriSquare TSX-300) that have different connectors. Example image:
