When Mazda upgraded the rear in 1994 they also had to change the driveshaft to fit the larger rear. It is 48mm shorter (L1= 1001mm vs 1049mm, 39.41/41.3" : L2= 864mm vs 816mm, 32.1/34.02) and used the larger 86-91 NA RX-7 pinion flange pattern of 4x67mm vs the 4x62mm pattern of the 1.6 rear.

Thank you this was very helpful! Would you happen to know the diameter of the shaft itself?
