Will this work?

So I have a 1990 4 door auto and am in the process of planning a double Dana 44 Waggy axle swap....Well I got a drive shaft and Tcase with installed Hack n Tap in the deal! Now, I have a 21 spline and the new Tcase is a 23. This Tcase and Dshaft are already matched to the axles... So, if I put a new Hack n Tap on my Tcase can I use the shaft? Is there a length difference between the earl/late 231 cases?

Anybody know?

you'll be able to swap the hack and tap to your t-case -


no problem.

remember that the seal housing needs to swap over too, along with the flange. :thumbup:

The "donor" case is a 96 and mine is a 90. both are auto 231....Any problems with that?
