Ring gear should be 7-5/8 (located on bottom center of i.d. tag)

'91 RS axle ratio -
V6 manual trans: 3.42 auto: 3.23
V8 manual trans: 3.08 auto: 2.73

Sure you want lower gears? Most people want higher gears, you lose a bit of top speed, but it gives you more low-end torque. If you want to keep it streetable, as a daily driver, I wouldn't go higher than 3.73.
