I have installed an Advance Adpaters fixed yoke kit on the NP231 in my '92 YJ.
In the new tailhousing, there is a threaded hole at the end of the part that the shift rail slides in to. It appears that lubricant will get to that spot. There wasn;t any sort of plug in the box that would fill the hole, nor was there any mention of it in the instructions.
I have seen pictures of the kit on some web sites, but none of them show a threaded hole there. Am I supposed to plug this? If so, where would I get the proper plug?
