I had 88-92 Mazda MX6 mirrors on my truck. They were an easy swap, just had to trim a little bit of the door with the Dremel tool and drill one hole. Here is the best pic I have of them.
Ya I did the toyota celcia mirrors on one of my first mazdas and the only thing is they look like droppy ears. still cool and for when I did them it took about 2 months before I saw it on 3 other mazdas.They do mount right in the same location and you do get a good veiw of the rear with them.
