I bought new wheel cylinders for the rear, and one for the front left from Kaiser Willy's and didn't have to drill or anything. On the rear, I did have to bend the brake line at a angle, but I put new ones on anyway, since the old ones were originals, and very rust. If your brake lines are rusty, replace them, they are cheap, and you can get them at your local parts store. I got my brake lines a o"rielly's. IF you do the rear, make sure you use a hub puller, not a drum puller to pull the drum off. Would love to see a photo of the car when your done.
