So I automated all the calculations now so I can easily write out the following given certain conditions:

Wheel diameter is kept constant at 24.685 inches.
All numbers correspond to MPH/1000 RPM, and significant figures kept to 3.

6th Gear still needs to be verified as proper input:

1987-1988 Turbo

1. 5.18
2. 8.89
3. 12.88
4. 17.91
5. 23.5
6. 0

1988 Convertible

1. 5.40
2. 9.38
3. 13.75
4. 18.78
5. 26.9
6. 0

1989 Convertible

1. 5.15
2. 8.95
3. 13.11
4. 17.91
5. 25.7
6. 0

1988 Automatic

1. 6.61
2. 12.19
3. 18.78
4. 26.09
5. 0
6. 0

5th and 6th are not used in the automatic, so those values will need to be inspected.
