Your Jeep has a 42RLE automatic transmission. It was new for the 2003 year. It's longer than the older automatic and you need to make sure you get a shorter shaft to adjust for it. I got my from Advanced Adapters. They make a kit that includes all parts (CV shaft and SYE) and have strong customer service. Just tell them what you have and they can figure it out. You can then get rid of your drop kit and get your ground clearance back. Good luck.
