Today I just finished replacing the old 91 XJ seats with seats form a Gran Cherokee. This was a three hour simple project after brainstorming the project first. The seats fit very nicely but some mods need to be done to the original Xj sleds/brackets that bolt to the floor since the seat brackets form the Gran Cherokee are way to wide. The trick is to weld two steel bars under each seat from the Gran Cherokee and than drill holes in the steel bars for proper fit to original Xj sleds / brackets. This was a lot of fun and the difference is unbelievable.
