My suggestion is to go to your local dealer and buy one. They may have to order it but should be there the next day mabye two depending which warehouse and how far your dealer from the warehouse. I had a different style of front JEEP on my 88 XJ. I have holes in the front panel where your JEEP is stuck on with 2 sided tape.
I do not know if your front and back JEEP are the same, but the dealer parts guy can tell you. That "information" is worth any $ you'd save on ordering it from some out of state web site. Also if the part is wrong the dealer won't make you "buy" it.
I know my front JEEP ran $60 but your stick-on version should be $30 or less.
Also owning an XJ it good to know the dealer parts guys, they will help you out when you need it the most!
