Thanks to all of you....I really appreciate the help.
One part confuses me - easily done these days.
That is the idea of centering the shoes. The installation instructions call for locking up the drum with the adjusting screw with the nut on the wedge bolt finger tight, thereby allowing the new centering plate to set the shoe-to-drum distance at the bottom of the shoes. Then the nut on the wedge bolt is tightened to 40 ft-lbs. This happens with the roller/pin combination sitting in the half-moon cut-out in the centering plate. Given all this, how does one center the front shoes? The only way I can think of would be to regrind the half-moons to move the shoes slightly - doesn't seem like a really good idea. What am I missing?
