The tranmission ratios below are for the Datsun 4WD 720 pick up, which has a transmission that will bolt right into a Z. The tail shaft housing from the 4WD pick up transmission needs to be swapped with one from a Z, however, because the one on the pickup doesn't have a place for the speedometer gear to go in nor does it have the worm gear on the output shaft for the speedo gear to mesh with. This may not be a problem on the 2WD pickups, but the ratios for the 2WD may be different too.
