Films for Juchipila, Zac.

The Family History library catalog does not list church records for Juchipila, Zacatecas prior to 1814. I'm looking for the record of Ygnacio Ocampo baptized in Moyahua or Contitlan abt. 1764 (married to Eugenia Carrillo).

How would I locate these records?
Thanks for any information, Roxanne Ocampo
