i put the darn thing inyway and it is running great! amazing what a better newer damper makes, i had forgoten. if anyone knows what that other sensor is please let me know. and thanks to the people who checked this post.
changing tranny tips: the 14mm bolts that hold the rear transfer case cross brace, 2 of them are tapered on the ends and fit into the bottom mount for the t-case. and other wise they all look the same!

well it did me..........
