I found a cup seal from a wheel cylinder with the same measurements that I need for my master cylinder except for the hole in the middle. Am I nuts to just cut a hole in it and install it? Everyone knows these parts are NLA.
I think you have come across the reason that people adapt other model master cylinders. If it were me, I would not "Jerry" rig anything in the brake system. Get proper new equipment.
