'91 AX15 and a '98 4.0 - Pilot bearing?

I can't seem to get a clear answer on this after searching, but I need to know what Pilot Bearing I need to get from the parts store that will fit onto the smaller end of the transmission input shaft and into the crank of the '98 4.0. A '98 and a '91 bearing won't work, I need a sort of hybrid. Any ideas?

I dont know if this will help you or not:
