Ok here are some tips on installation. Now keep in mind this is how I did it, it may not be the correct or best way to do it. But it worked for me. 1st thing I would do is get the shifter all put together. Try and get at least one teflon washer in between each of those shifter handles. Also I attached all the cables to the shifters before anything was installed in the truck. I had to clearance the side of the shifter because one of the bolts that connects the cable end to the shifter handle would make contact with the shifter housing, little work with the die grinder and all the levers could be moved all the way forward and back.
Now I mounted the front and rear brackets to the np205. Next I went ahead and mounted the np203 bracket using those two long bolts and metal sleeves. I had to clearance my bracket a little since it was hitting the transmission. While I was down there I mounted the little bracket to the np203 shifter bolt.
Then I moved on to the bracket for the rear output rail of the np205. This mounts to the front 205 bracket you installed earlier with that large allen bolt. Don't tighten that up yet because you want to make sure that it will bolt to the shift rail....mine didn't. The hole was already elongated but it still wouldn't line up so I had to oval it out even more. Now you want to start to install that really long threaded rod. It goes through the front and rear 205 brackets, make sure to put a nut on both sides of those brackets dont tighten everything up just yet.
Now I went ahead and started installing the cable ends that will mount on the t case. It's up to you where you want to attach what cable to what shift rail. The 203 is the easiest so I did that one 1st. Next you will want to hook up the cable to the 205's rear output shift rail bracket, this one is kind of a pain to get to. Make sure you put on the small triangle shaped bracket with 3 large holes and 1 small hole 1st otherwise u can't get it on. Hook up the cable end so that all the teflon washers are on the underside of the bracket. This will space the bolt head down so that it won't make contact with another piece that u still need to install.
Now u need to install the smaller threaded rod and the long metal sleeve. I took the grinder and put a flat section in that tube because it is quite close to the bolt head that u just installed on the 205 rear output shift bracket. When u are ready for the final install, I used blue threadlocker on this since there isnt much thread engagement. once the small triangle bracket is on there, install the nut. Now I would tighten the cable nuts on all the installed cables.
Last cable, pretty easy one. This one goes through that small traingle bracket and mounts to the 205 front output shift rail. Ok I think I got everything. I would mount all of this hand tight once just to see what you are working with and get familiar with it. Then go back with your wrenches and tighten everything up. I had my setup in and out of the truck probably 5 times before I mounted it all for the final time. I'm off to the airport so hopefully this helps and Im sorry if any of it was confusing.
