what gears does my lincoln have?

[Soon2beBlown]

I have a 1989 lincoln towncar with a 5liter efi and AOD tranny...anyone know what rear gear ratio these came with? and would the whole rear end be swappable into a 90 GT?

3.08 most likely and i suppose you could since it is a 8.8 rearend check the gear box under the car on the rear axle
