These are door shim spacers for Land Rover Series 3. These differ from the 2a Shims as the hinges are more squared.

Land Rover Series 3 Aux Power Strengthening Plate. This little plate fits snugly into the cut-out where the Auxiliary power output (used for inspection lamps etc) appears on the dashboard of a Series 3 Land Rover (1972+) as the plastic dashboard can become brittle with age, and repeated use of this can cause cracks or pieces to come away. This slots into the recess and at 2mm doesn't affect the brass bolt lengths as they pass through into the dashboard behind.
