Tamiya 1/24th Eunos Roadster number plate sizes?

I've been asked to produce some UK number plates for a Tamiya 24085 1/24th Eunos Roadster. Unfortunately as they are a gift the person I'm doing them for doesn't know what size they need to be (the kit is on order).

Could anyone who has this model measure the front and rear plates for me?

It would be most appreciated.

Many thanks

My measurements were 14mm by 6mm for the MX-5. They maybe a little off because of how small they are!

That's fantastic, most appreciated.
