Kelly,

As Lynn alluded to, they cut/grind down = the 13B=20 rotor housings to the 12A width. Side housings for a 12A can be 13B = early Cosmo=20 housings which have the seal groove in them rather than the Rotor = housing. You=20 can mix and match most parts if your prepared to modify. Powersport = actually=20 used a 12A e-shaft in their very light motor, they just reduced the = centre=20 housing thickness.

I'm using a 13B Cosmo rotor housing = (big exhaust=20 port) with an RX8 rotor with 3mm apex seals and 13B end housings ( = Bill=20 Jepson's light carbon housings- when available).
