84-99 Xjs had HP D30s but your best years to get are 92-99, or 95+ due to bigger ujoints. 84-94 used a smaller ujoint, but you could always put your TJs shafts in to get the bigger ones.

You will most likely want anything 96+, which was the year they switched to the 297 ujoints (stronger). Also, very early models had vaccum disconnect.
