Is it possible Haynes manual lists the wrong pilot bearing in the pictures. My clutch kit has both the 4 and 6 cylinder bearings. The one Haynes shows as the 6 Ax-15 does not fit my transmission also the one it shows for the 4 AX-5 was in my fly wheel. Is there the possibility that the person who owned this before me put an AX-5 in instead of an AX-15? Its a 91 YJ 4.0l
