Rear Calipers
 

Realized I posted this in wrong section, but bought first Gen race car. It has rear discs that need to be rebuilt, how do I know what calipers on it? 12A or 13B? New to RX7's and can't find any kits local, what is best source?

the 12A had non vented rear rotors, 13B/gsl-se were vented
