Finally getting around to installing a 04 TJ 231J in my 90 XJ with an AW4 trans......Here is my probs,first the 04 231J is out of an Auto TJ,which the input gear is longer and 23 spline..no biggie...so I order a 91 XJ 231J 21 spline input as they list 23 spline and 21 spline for that year 231J and this is the last year they do ask for 21 or 23 spline and my 90 XJ uses the 21 spline..........so happy me tears down the 04 231J and try to install the 21 spline input gear....does not fit the plantery,same teeth count,but the 21 spline input gear,the outer teeth that rides inside the plantery set are not cut deep enough..so it does not fit inside the planet carrier....So I have a junk 96 231J and rip it down to see if the planetery is different then the 04 231?..well the same...ratts...to make a long story short,what part numbers do I need to install a 21 spline input gear into a 96 and up 231j?.....Do I need the early planeterys and anulus gear to match the 21 spline?..or is thier some super secret 21 spline input gear that drops into the 96 up 231J t cases?....................Thanks,
