73 up disc brake conversion. Is my caliper going to work when revesered to oposite sides?

There are longer Chrysler hoses, like F-body, if you don't want Chevy parts on your mopar. And IF you want to leave everything as is here is what some do.... Simply flip the calipers over so the bleeder is highest. Open bleeders and allow to chicken or free bleed remaining air out. Remount calipers and carry on.
