Arm-rest Cubby

All models got an extended centre console with arm-rest and cubby under for the 1972 model year. This is my 75 V8.

Showing typical sideways play of the lid before fastening ...

... which can easily break the peg on the lid in its original orientation

Peg removed from mounting plate ...

... turned round through 90 degrees and refitted

Showing the clip after turning round through 90 degrees, and the curious recess and marks looking like blocked-up fixing holes (75 V8)

If the underside of your lid looks like this, the socket is being pulled out of the base! Lever it off carefully using one screwdriver each side to avoid breaking the peg.

In which case you can fabricate a mounting plate like this to hold the socket more securely, which will drop neatly into the recess.
