Dispensation records for Zacatecas

Are there specific films for Zacatecas where the dispensation records that are in La Sagrada Mitra can be found? The book is very expensive and not really available as far as I can find. I would like to know if I can order the films the records are taken from from the LDS history center. I'm interested in the Jerez Zacatecas area's since so many early families intermarried. I've done the marriage information records and hey say when they are related but not who that person was 3 or 4 generations ago who was the trunk.

I have taken my Caldera line back as far as I can with the records available at the LDS but found a decendant intermarried and it connects my ancestor Joseph Antonio del Carmel Caldera abt 1735 and Manuel Caldera abt 1740 as brothers so I was hoping to find their parents in a dispensation record. I understand this record to say in the 3rd degree they were brothers, 4th degree was the trunk?
