First of all, I don't own an rx-7.

I am trying to do a brake upgrade on my 1987 2wd Toyota pickup without using aftermarket ($$$) rotors. rx-7 rotors may work, but I have not been able to find the dimension of the inside diameter of the rotor hat. Anybody have a rotor handy they could measure? I don't know if they changed after this, but I have been looking at 93-95 rotors.

Thanks for any help.
