I used to have a large number of old MX-300S Radios and now down to a few dozen that all function but with everything, time had taken it's toll on the rubber parts and I hate to scrap them. I would like to find some Rubber PTT Pads or Covers (Motorola 3205427C04 PTT BOOT SWITCH). If anyone knows where to find then that would be good. I had a friend create a Solidworks STL of the components which are three but the dimensions are incorrect and made of hard plastic not rubber. I am hesitant to move forward as manufaturing them might be prohibitive costwise. It may be time for the Boneyard unless you guys have any input! Thanks...
