Some back ground. My Truck is 1992 W350 SRW with the Getrag 360 5spd. Last winter I was plowing and something broke in my old 5spd. I was only able to drive home in 4th gear only. With my 3.07 gears 4 low was needed lol.. and I had to smoke the clucth to get going..

Ok, in order to do the twin stick NP205 conversion you have to modify the transfercase shift rail. You need to remove the transfercase from the truck inorder to access it. Drain the oil out before removing it... Remove the transfer case shifter from the trans tail housing, and set it aside, we will be modify it later. You need to remove it any how, to unbolt the transfercase. With the Transfercase out ..clean it up. Remove the shift linkage bar from the shift rails. You need to unbolt the trans to transfercase adapter, and the pto cover. The adapter has several bolts inside the adapter. In order to remove these, you have to remove all the other bolts, then use a short swivel socket to access the inside bolts. You may have to loosen the bolts and pull the adapter off at the same time or your socket may become trapped etc. Now the shift rail that we need to remove is the one closest to the input shaft ( or Trans ). This is the rear axle shift rail. The front axle shift rail is the outer shift rail next to the front yoke. The trans adapter had to come off to allow the rail to be pulled out. To remove the shift rail you need to pry out the rubber plug that covers the shift fork roll pin access hole. Also there is a detant ball that has to come out with a magnet. So after those parts are out you line up the shift rail roll pin with the access hole. A flash light helps alot. Drive the roll pin out of the shift fork. The pin will fall down into the case. You can get it from inside the pto port. Keep the punch in the shift fork to prevent the shift fork from pivoting away from the hole. You can reach up between the gears with your hand thru the pto port and try to adjust its position when you are reinstalling the shift rail later. Remove the shift rail from the case. You need to grind it in two spots to allow the 2wd low position. You can purchase new modified shift rails also. I did, but I copied the grinding onto my old rail, so I could use the new shift rails in another project. I got these pictures from the internet.

Now reassemble the transfercase.
I had my "broken" getrag out so I used it as mock up to build the twin stick shifter. It made it ALOT easier building it out of the truck. I had purchased a Jb customs NP205 Twin Stick kit for a chevy. It is made from stainless steel and has 5/16 heim joints. The stainless is hard to cut and drill. It has nice shifters and I bought the aluminum knobs that have the shift pattern milled into them. The chevy kit has the shift levers taller and on a offset. These Shifters wouldn't work with the 5spd getrag. One way the shifters would hit the shifter of the transmission, and the other way the shifter would be blocking a lot of the passenger side area.

I eventually plan on adding a NP203 range box to the front of my np205 to make a doubler. Then I would have 3 transfer case levers

I have been talking on Pirate 4x4 's web forum about this . Here's the link -http://www.pirate4x4.com/forum/showthread.php?t=839938&highlight=doubler . I already have a Junk yard NP203, which I think is from a dodge???. I have to take it apart and figure it out. My Cousin is a machinist and hopefully I can pay him to help me. When I do this in the spring I plan on a nice dual disk clutch and new drive shafts at the same time.
I also modified the Getrag Shift cover to have a lube fill port and a dip stick. this will alow easy fluid adding and checking. I drilled and tapped the cover for a 1/2 " pipe plug. One 1/2" plug has a 3/8" steel plug that is threaded into it. I plan on welding a long steel rod into it to use as the dip stick. Pictures to follow.
Here are some good links on general np205 twin stick conversion etc:
