Our replacement differential bungs are made from solid brass rod on our CNC machines and unlike the original castings, these are not prone to cracking and we have added a wire hole.
These plugs are used on the Elan & Elan + 2 as differential top up bungs and also Elite, Esprit (up to 1993) Eclat, Excel and on most of the twin cam engines as sump bungs.
The original part number would have been A036R6014Z
