okay this is weird, i have a '76 Mintgrün 02 and a Subaru wagon too (albeit a Liberty RS Turbo one) but thats still pretty weird.
you have great taste sir!
I'm tossing up on the Euro plates we can get in Australia, or reprints of the period correct Australian B&W plates that ranged up until 1980 or so. We have a lot of options for registration plate styles here.
