I think I found my huckleberry, I was digging around a pick and pull today and found a VIN H XJ which is an 87 I do believe. It had a 5 speed in it, It was raining so I didn't get under it but I thought the 87 XJ 4.0L had a BA10/15 and those are 4 speeds right? So it would be an AX15 if a 5 spd, right? Thanks for any info. This one has a 5 spd is why I am asking and that baby is mine if so.
