If you have information to reference please include; year, EEC part# (off eec), software tag (off eec or sticker passenger side top of fender under hood), calibration (off sticker inside drivers door jam), rear axle (ratio or letter under AX code on sticker inside drivers door jam)

Dealer's order auto's with an axle ratio of 3.27. 5-speeds came with a 2.73.
I know you could order a 3.73 from the factory in 1990 though.
