Need a measurement on Late model Z31 Rear Calipers

Well, I'm doing something Unique again. This time its a rear disc brake conversion and I will be using Late Z31 Rear Calipers (the wide ones that use vented rotors).
But I will not be using z31 rotors. Before I order Parts there are two measurements I still need to make sure everything will go together and clear the inside of the wheels.
I would greatly appreciate it if someone pulled off their rear wheel and gave me an accurate measure of the following; (see picture below for clarification.)

Measurement "A" - Distance from rotor to outboard edge of caliper bracket. (this is the one I need most)
Measurement "B" - Distance from rotor to outboard edge of caliper at its widest spot. (I am aware that this measurement shrinks with pad wear, so please tell me if your pads are new, 50% almost gone ETC)
Measurement "C" - Distance from outside edge of rotor to tallest part of the caliper

I find using the probe that sticks out of the bottom of a vernier calipers does a really good job for "A" but you gotta get a little creative for "B"

Thanks
