Swapping for an OD 904?

Actually, I did mess up

In 1980, many rear drive Chrysler, Plymouth, and Dodge vehicles were given a wide-ratio version of the TorqueFlite, dropping down the first gear from 2.45:1 to 2.74:1. Second was moved from 1.45 to 1.54; third remained at 1.:1, reverse at 2.22:1. All Torqueflites adopted this gearset in 1981.

I was thinking of the wide band ratio.
