Mk1 Coopers and Super Deluxe 850s were fitted with supplementary oil pressure and water temperature gauges in an oval gauge pod. The original and reproduction thin plastic covers (14A9815) for the gauge pod require the use of both the original plastic speedometer-only pod and this metal adapter plate, which is attached to the face of the underlying speedo pod by way of a pair of brackets (24A0053K). This plate is now available as a reproduction part; includes screws.
Note that only the early Minis use this arrangement. Later Minis with three (3) central pod gauges had a thicker all-plastic pod which is self supporting and holds all of the gauges with no mounting plate or adapters and does not rely on the speedometer to locate the assembly. See 24A2702 for details of the later pod.
