Sounds cool, altough my ride is 5spd sticky.
I have the following parts for it: FC S4 13B (146HP) complete with everything, 12A Front Plate, FC gearbox and RX7 SA Rear End with Disc Brake(4*110 Bolt pattern).
I heard, the normal 323 FA can be modified in order to fit 13B, because its impossoble to find here RX3 crossmember. I also short of money a bit, I can use what I find here. I also heard, many RX7 SA parts bolt on 323FA, for example the front suspension with bigger brakes, is it true?
Can I use the original RX7 FC driveshaft or just this 1300 drive shaft?
Do you have some link maybe photos about your 12A 323?
