Wills from San Miguel El Alto and Valle de Guadalupe

Could anyone advise me on where to find Wills for these two cities? I have not found any microfilms on this information yet. Also, land records? I know some lines I am researching owned land. I have looked at the Fort Wayne Indiana genealogy library, but they did not have many Mexican records. Thanks for any guidance! Hoping for information from the Internet or in the midwest.
