most all dealers have to send any cluster or radio to a Q one certified repair place. Q one (iirc the name right) was fords standards, and all of the us cars followed suit.

my ex used to work for one of the repair places, her dumb boss refused to up date his work stations and he lost his cert, and all his business too, closed up shop soon after.

guy had some stock too for old cars, nos stuff. you called him for a 63 vette am radio, he had one lol wonder where it all went.......
