Where are you looking?
Rock Auto normally has pretty good application information. If you really get stuck, you can look up what the GM part number would be at a GM parts website and then try to match that to aftermarket ones.

That refers to the overall height if you lay the rotor down flat. I believe the taller one is for the parking brake shoes that are inside the "drum" part of the rotor and the shorter one is for parking brakes that are built into the caliper, but don't quote me on it.
