73MB,

It wouldn't hurt to grind a break line.

If your rotor is like mine was, the parking brake shoes get caught in the lip on the inside edge of the drum in the center of the rotor. If you are able to back off the star wheel enough, the rotor should come off. But sometime the adjustment screw is rusted tight. I put Never Sieze on the adjustment screws when I reassemble them.

You will find it is difficult to install the springs on the brake shoes. You just have to persevere to get them on. Before you take the old parts off, make a note of how they are installed.
