Hi Mike ...
Mexican Ford dealers is where you get the parts from, down here. They get the parts from the States.
There is 2 or 3 Ford assembly plants in Mexico for engines and complete cars. There is also some other Ford suppliers or Ford owned manufacturers such as Carlite (glass), Visteon (upholstery, electrical subassemblies, etc), Tremec (manual transmissions). All of this for new cars.
If you want old car parts, there is none .... we get them from you guys up there.
I do not know what are you looking for or what is in your mind......

need more input froom you.
I'm sorry, please be more specific.
Saludos,
