Outer Limits 4x4 Board

hope fully someone can help

i've got 1994 hzj75 and she's got some unhealthy noises in 4th and 5h and i had bought a hj60 for 2k for a motor a few years back and recently decided to swap the gearboxes over and come this morning pulled the box out of the 75 and relises the input shaft is a different spline and length and i'm looking for the easiest and cheapest way to solve this problem.

any info would be much appreciated

Swap the input shafts.

is there an easy way to do that from what i see i need dissemble the gearbox

Not to sure myself sorry, go over to iH8mud forums I think some guys there have a description on how they have done it.
