Howdy mshunter,

I did the same thing that it looks like you are trying to do, in Alaska.
Have attached a link to a thread that describes some of that, and has more links to info on the route to getting your A+P via OJT rather than military or civilian formalized schooling.
As far as auto mechanics becoming certified aircraft mechanics- go for it. Your background, while not "traditional" would make you a prize I would think for a company looking to hire a good wrench with a solid work ethic.
PM me if you need more info.
