Nv3500

Is it a AX15 or a NV3500? The 3500 is a large trans, and will need a bunch of tunnel mods. If it is out of a Dakota first gear will not be as bad as one from a 1500. Have you looked in some yards local to you, you can find the 15s and the 3500s somewhat easy. (lots of Dakotas in yards)

The account selling it classifies it as an nv3500 out of a 94 2wd Dakota
