Yes, final drive == ring and pinion ratio. Actually the 3.89 from the MC
should give the '91 a lower rev/mph than its normal 4.11, all other things
being equal (including the rear diff swapped as well). I think the lower
numerical gears in the 3B may be used to take advantage of the higher
redline of the 20v engine in the 1-4 gears, compare mph/1000rpm in an MC to

backdate a 200q20v with a 10v 200 tranny, for repair reasons, I would need
the 10v rear diff as well, and this would result in the motor spinning at a
higher rpms than normal for a given mph, right?
