as far as i can tell, nothing bolts to that.. nothing did on mine..... (apart from the 4x4 indicator light switch)
i need to go under my car at some point in time to spin the prop shaft around as it vibrates when i go over 65mph.
i will do a video for you and try to get some of the 4x4 mounts, linkages and other things in detail for you.
i may do it tomorrow afternoon, as i am doing voluntary work in the morning.
