The distributor in 4age motor is on one side near the fan or closer to front, contrary to other 4a machines in which distributor is above the flywheel. Position is distributor is speciality of 4age which makes it suitable for RWD. With any other 4a engine if used in RWD (like ke70) the chassis will have to be cut and heater and dashboard altered. I am surprised to this version of 4age which has distributor above the flywheel, and make it difficult to use in RWD.
