Brake hat height

Hi there, if any of you kind souls out there may be able to help me out...thank you in advance...

Was wondering what is the height of the front and rear brake rotor hats?

If you refer to the above link, on the top of each page is a diagram of a rotor. Would like to find out what is 'B' 'Original Height' of the front and rear rotors of post 1999 VR4s and if any of the rotors in the Mitsubishi section are compatible for use.

Cheers!
Sam
