Number plates and old dealer details

Hi sorry i know ive seen it on here but cant find it.
i need some plates making up and need recommendations for where, what style etc. Also someone had a picture of a list of old dealerships. I would like the authentic look with the dealer in the plate footer text.
i have a 1980 tintop btw.
cheers and sorry for being a typical bloke who cant find stuff even when he tries to look for it.
