upgrade master brake cylinder

Have you even used a pressure bleeder? Makes vacuum bleeders seem stupid. I used vacuum bleeders for years and there’s no way I’d buy another one of those either.

If folks want to use the old cast iron master cylinders that’s fine, but let’s not pretend they’re easier or better.
I'm thinking about converting my bone stock 1974 Duster with its original power front disc/rear drum brakes to the Mr. Diff aluminum and plastic MC referred to in this thread. How hard is this to do? Do the brake lines thread in correctly? Is there anything I need to do with the rod that comes out of the front of the vacuum booster? Thanks.
