String spacing question.

What is the American standard spacing and what is the American vintage spacing ?
I remember reading somewhere about 2-1/16" being the Mexican and vintage spacing, is that correct ?

Pretty positive the vintage string spacing is 2-7/32", and I believe but am not positive that the American Standard is 2-3/16". And yes the Mexican is 2-1/16", unless it's a Classic series then it would probably be vintage spacing too. I just went through this ordeal in trying to find the correct bridge for my "aftermarket of unknown origin" Strat body.
