I went to my friends transmission shop and he supplied me with a pilot bearing for a Cummins engine (Dodge 4x4). I think it was an '04. The pilot bearing has a lip or flange face on it that probably extends out 2-3 mils. I'm just guessing at that depth. It goes in just as far as the regular pilot bearing, but the lip gives you a lot more support I believe. Fits nice, can't see it hurting anything.
