Thanks A-Snake. Good information there.
Here's the dash area on CSX2128, where it can be seen that the Moto-Lita SW (supplied by AC factory) is attached with slotted screws, as is the dash as well.
The Sun tacho and the switch panel are Shelby add-ons, and are retained by Phillips headed screws, as well as the shifter boot retaining ring.
Cheers,
Glen
