can you put the bolts through the master, hold it in place, with your fingers on one of the bolt heads and the palm of your hand holding the master in place, then hold the plate with the other hand, and twist t he bolt with the fingers of your fist hand?
Another thought is to put longer bolts with the head cut off (or a piece of all thread) in the nut place, and put it in place and slide the master on the bolts, then clamp in place, and pull one bolt out and replace with one of the originals, and to the same to the 2nd bolt?
