You have a Ford bearing. The one you want should be fairly easy to find. Make sure you measure from the bearing face to the flat at the fork clip.
You are schooling yourself on putting a clutch in a Jeep. You are going to have a steep learning curve. But, the second time you do this will be MUCH easier and quicker to do.
More than likely you will need to rebuild your Bellcrank. It's not difficult, but necessary for good clutch feel. If you remove your Bellcrank make sure you reinstall it correctly because the lever arms on the crank are different. Be aware that when reinstalled the lever arm angle is critical. When I installed mine the first time the clutch was almost impossible to use. Once the crank angle was worked out I can work the clutch easily with one hand. It's not rocket science, but pay attention to that detail.
