Carrier tail light

[Tom Millward]

Can anyone tell me the correct style of rubber tail light for the early Mk1 Carrier. I bought a Rubbolite no5a, but now I have my number plate I can see that it doesn't fit. Dirk Leedwater has what looks like a Canadian rubber tail light that would fit, but it has no number plate cut out. Should there be a number plate cut out?

I have considered modifying my No5a to fit, but don't want to cut about a rare tail light if I don't have to.

Thanks
