    Anyone have some links to pictures of the various Transfer cases, Dana 20, NP 203 and NP 205?

    Thanks

    I don't know if this is what you need to know or not, but I have an easy way to tell if you have an NP205. On the back of the T-case look in the center of it. The 205's have a small circular piece of metal with 3 bolts holding it down. Its almost like a big silver dollar with 3 bolts in it. Anyways, the 205 is the ONLY one with that. Its how I tell the difference. I don't think I've ever seen a Dana 20. They mainly went in 3 speed trucks with smaller engines. And the 203's are easy to pick out just because they're so big.

    The only GM application of the Dana 20 is in 1st gen. Blazers. Most of them were in '69 and '70s, but they were used through '72. Maybe a few '73s or '74s had them also?
