I haven't seen a bypass pulley for a 97+. I'm not sure why they don't list them, I think the compressor mounts are different.
I don't know of a ac delete belt for the 4.0L, I think they all had them.
If you have a Sanden, pull the AC pulley from a 96 and earlier. The 97+ units pressed and crimped the bearing into the pulley, pre 97 the bearing assembly is simply clipped in.
Remove the front nut, remove the clutch plate, and remove the e-clip from unfront of the pulley. The pulley can then be removed.
When you get the assembly home. remove the nut, remove the clutch plate, and the clip in front of the pulley. Remove the pulley and what is left of your bearing. Slide on replacement pulley, and re-use your old clutch plate.
