short update,
Installing escutcheon and push buttons onto the tuner unit.

Original style press on push buttons could go on anytime, but since mine lock with a set screw they must go on before the escutcheon, which means they have to go on before the tuner unit is installed into the main housing.
This also means that once my radio is in the truck, if i want to remove a push button, the radio has to come out and be disassembled. This situation is not ideal, but it is something i'm ready to live with for my home made push buttons.

The backplate pointer goes onto the tuner unit first.
Next my home made push buttons install from left to right.
Finally the escutcheon slides over the buttons and screws into place.

Warning:
When removing the escutcheon assembly from the tuner unit, remove only the two Escutcheon screws and pull it straight off.
The Backplate pointer must remain screwed to the tuner unit.
Never unscrew both the Backplate Pointer and the Escutcheon assembly simultaneously.
The Backplate Pointer is sufficiently tight into the Escutcheon that the two will want to travel as one, this order would seriously risks breaking off the pointer.
