Just want to reply to this thread again i couldn't find any Ruben Olivares, fights except for highlights. But this great uploader recently has uploaded the first two Chuco Castillo fights.

And a few other early Ruben Olivares fights with Ushiwakamaru Harada, Tiny Palacio, Walter Seeley, and theres more to come. Hopefully he uploads the 3rd Chuco Castillo fight, and the fights you mentioned Mick.
