Are you mounting the taillight on the top centre of the number plate attached to the POL container as mounted on the armoured battery box?

Depending on the production month/year, your taillight could be the rubber housing holding the pinhole lens, or the later all metal housing holding the coloured lens. If you have rubber firing rests, I am of the thought the rubber housing may suit your needs. Plenty of them around as they are quite similar to those found on CAB 11/12 CMP’s.
