They were an option for select models on Japan as well, but here are their lights:
These are the Japanese version with center garnish, but the Mexican look identical without the center garnish. I'm refinishing a set of stock bucket tails and would seriously purchase a set of the Mexican bezels. Or a whole unit, whatever.
I'm not too familiar with current ongoings of junkyards in Mexico. It's been a long time since I've been down there. I would PM some of the Mexican members and ask a few questions. Maybe they are familiar with the area you're headed to.
