I have a 87 xj with a aw4 and a np242 t-case
the case snapped the out put shaft..I pulled it and its 21t spline count
I found these are in 87-89xj and 4 banger models..and alittle tough
can I swap in a newer aw4 tranny with a 23 spline ? Is there any difference
or will it bolt right up...I figure I'm in this boat now so why not upgrade to a stronger drive line and parts are everywhere for a 23t...
any info would be appreciated ..
Thanks in advance...
