The older (87-90) AW4's had a 21 spline, and went to 23 spline in 1991. Get a later tranny, since to replace the output shaft you'd need to tear the old tranny apart anyhow.

Not sure if the computer would wire up either.

Are you talking about a Chevy NP241 or a Jeep NP242?

Since he mentioned 4:1, I think he's refering to the NV241OR(Rocktrac)

AH, I see. You'll need a 23 spline output AW4, you'll find them in the later models (I think 95 plus?).

Pay close attention to the input on the t-case to make sure it's the right length so you get the proper contact on the transmission output seal.
