The 203's are ok T-case's, but if depends on what you are going to do with it. I have put a part time kit in one and never had any trouble with it, but I wouldn't use a 203 unless I had no other choice. The chains are really bad to stretch and brake, any serious off road use go with a 205 all gears in them, but a 208 is a tough T-case and it has a lower low range than any of them.Just my 2 cents hope everything works out Axe
I had a 350/TH350/NP203 setup in my 1977 Blazer. The previous owner had done the part time conversion on it. It was fine, but I agree the 203's have a weak link (pun intended) in the Chain Drive. I broke it a couple of times.
I ran the Rubicon in that truck. Of course, I wouldn't do that again, full size trucks are just too big for that route.
