Pilot Bearing ?

Great timing. I'm wondering about this myself. I've got a 99 5.9 that I'm putting an AX-15 transmission behind. I bought a clutch kit for the 98 3.9L Dakota (truck the trans came from) and the pilot bearing absolutely wouldn't go in the 5.9. I even put the bearing in the freezer overnight and tried using assembly lube to get it in. Finally I went on Amazon and ordered another timken bearing, should be here Tuesday so we'll see....
