just to confuse things !
my misses 1.0 basic 96 k11 has the early g/box with a low ratio diff (screams at 70 even with 155/70/13,s)
my 1.0 micradot 94 has the early g/box with a high ratio diff (cruises at 70 with smaller 165/55/13,s)
my 95 super s had the later g/box (totaly different casting with a 4 inch steel cover bolted on the outer end) with a high ratio diff
