Jim - if you look at the Needswings Skreem page you will see a video where they hold up the part and you can clearly see the numbers. I think you can still order from them but no ETA for delivery. That's why I'm trying to get FCA to provide them. Unless someone knows something I don't, a used one won't help you without your secret code number installed. This scenario reminds me of working for the DIA in Berlin back in the sixties. Maybe my top secret crypto clearance from those days will help with FCA, but I doubt it.
