I have heard rumours about 2 12AT Cosmo`s being registered in Norway (imports)
Why not try too contact some of the local rotary guru`s and ask if they can help you get in touch with the owners, if you succed and manage too get the chassie numbers of one of those cars, you can probably get a helpfull Mazda dealer too do a search for part numbers on the brakes and cross reference them with the brakes on your car, if the parts are identical a helpfull shopmanager should have no problem with giving you a signed paper that can dokument that.
Thats how i got my turboed GD Coupe legal, i dokumented that a MX6 GT could be legally registered in Norway, AND that the brakes on my 16v GD was identical too those on a MX6 GD.
That was enough too get my claimed 170hp (probably not the whole truth

) written in the registration docs)
Remember, the guys at "bilsakkyndige" are allowed too use common sense, you have just too find someone whos willing to do just that,
