I always liked my 203's as full time.  The kit saves some mileage, but not a great deal and it does cut down on wear on the front axle, but again, go through the frontend and replace the joints and put in some good greasable ones and service them when they need it.  Course, I like the front drive flanges... when its time to play I just drive in rather than get out and lock the front or hope the auto hubs work, my stuff is tied in forever.

I have an extra factory crossmember, and I have considered bolting that as shown and mounting some steel to it. With my truck being a long wheel base, I would hate to tear my 205 up if I got it high centered!

Yes, (that's what 's on mine)  You just need to find the transfer case with the correct input shaft.  Don't quote me on this, but I believe the th350 was 27 spline, and the th400 was 32.  If you are going to do more than putting a part time kit into the 203, personally I'd be looking for a parts truck.  You'd have the trans, transfer case, adapter, crossmember, and driveshafts if you needed a different length.

If cost is a factor, I wouldn't discount the 203, how many years did it run in your truck before the teardown?

The NP205 is worth every penny.  :)

I have seen these things hold up to some pretty radical 4x4 truck pullers with out fail.

Also, I didn't see it mentioned yet, but the NP205's ID tag is on the front of the case underneath the 2 shift rails.

It is typically a square piece, especially on the older models, and not round like all of the other NP/NVG t-case models.

I just realized a week ago that there is a difference in input shafts for the np208. I had a 81 208 that was behind a th350 and the shaft was smaller than the one behind my 4 speed. Make sure you get the right one for whatever trans you decide on. Whole parts rigs are the best.

I put a mile marker kit into a 203 about fifteen years ago. I can't remember the particulars but it was easy, worked perfect, and I used that truck for mud bogs. Never had a problem with that 203.
