Well as of now, I have two bellhousings in transit. One is the pre-magnum truck bell as shown in KWGoose's pics. The 2nd is some kind of anomaly. The prior owner told the guy I bought it from it was stock to his early 90's Dakota. It is a fully enclosed bell with a dust cover like an auto trans. It is actuated by a hydraulic slave cylinder. It has a center register hole, unlike what an AX15 Dakota bell has. The register measures 5.125 like an 833od, and it has four bolt holes in the corners. Scratching my head. The original owner claimed it was stock to his early 90's dak, and he put a 340 in front of it, and used an 833od. We will see about that. However judging by the pics, there seems to be plenty of real estate to weld and drill, in the event the 4 bolt holes aren't right. Stay tuned!
