Mazda didn't make the whole car by themselves, they bought parts from different vendors, and i had started making a list, just because its neat to see what it took to make these cars, but i ran across this list in an old bulletin book. Mazda still uses most of these suppliers now.... these were actually by part type, and maybe i should have photographed it that way

 

Mitsubishi electronics such as alternators and dizzy ignitors. Perhaps some relays and other things.

 

its funny that those are not on this list.
