Joe,
I would save your money. Your XJ came with a 8 slot grill so that is what it is to have.
A while back I found an aftermarket site that sold billet metal grills. He was taken to court by DC and posted the history of the WW2 Jeep grill.
Go ahead and spend your money on a FORD designed grill. To me what DC has done with trying ot make the seven slot grill a trademark is a low point in JEEP brand's history.
Very interesting reading every XJ owner should know this.
Here is the link to his site for the write up:

Here some of his story you can read it all on the site.
"The facts of this particular case began as far back as 1940 (while World War II war was breaking out in various parts of the world). The U.S. Government requested that automobile manufacturers bid on the development of a powerful but small and lightweight vehicle for reconnaissance and transportation purposes (The beginning of the jeep). The three companies that ultimately succeeded in getting contracts for this vehicle were BANTAM, WILLYS-OVERLAND, AND FORD MOTOR CO.
WILLY'S-OVERLAND was the predecessor to the Jeep Corporation, who was the predecessor to DaimlerChrysler Corporation at least with regards to the current Jeep vehicles (American Motors and Kaiser fit in there somewhere). The important point to this story is that Willy's and Jeep are all predecessors in interest to DaimlerChrysler Corp. which is now running the show.
BANTAM (the smallest and hungriest of the three) received the first contract (for a prototype vehicle) and produced the very first jeep vehicle - This vehicle met the basic expectations of the Army, and after testing, the Army decided to make some changes and issue production contracts. In the mean time Willy's and Ford decided to provide prototypes of their own (at their own expense) so that they could keep their foot in the door.
WILLYS-OVERLAND ( DaimlerChryslers predecessor) received the first production model contract based on its more powerful engine and lower overall cost - and proceeded to produce the jeep vehicle while incorporating changes that were directed by the Quartermaster Corps. One of these directed changes was to incorporate a grill design similar to the one FORD had patented and used on their earlier prototype. This early grill design was a fabricated grill of welded iron bars - similar in construction to a heavy duty Bar-B-Que grill. This is ironic that the company that later claims to have been all-knowing all-seeing with regards to the jeep was directed to use the Ford style grill and to dump their own design.
FORD MOTOR CO. was then offered a contract for a similar number of jeeps (comparable to the Willy's-Overland contract) providing that Ford would agree to build them in such a way that all parts were interchangeable with the Willy's-Overland model.- FORD agreed and immediately began tooling up for production. This contract was issued because the Army didn't have the confidence that Willy's could keep up with the demand.
One of the first things that FORD did after they received the contract (in October 1941 shortly before Pearl Harbor) was to re-design the front grill so that it could be "Stamped or Pressed" out in large quantities and still be interchangeable with the heavier grill that Willy's was using on the MB. The advantages of this grill over the Bar-B-Que style grill that Willys was using was that it was interchangeable with, easier to produce, cost less ($8.00 vs $26.00), weighed less and provided the same degree of protection to the front of the vehicle - It was commonly referred to as a "Radiator Guard" since that was its primary function. Again, Ford takes the lead in the design of one of the jeeps most recognizable features, and Willy's just sits there and brings up the rear.
Willys-Overland continued to produce the welded bar grill design until approximately April 1942 - at which time they changed over to exactly the same pressed steel grill design that FORD had originated. This must have been hard to swallow for them at first - but then considered the bottom line. There is no indication that Willys was forced to change to this new design; therefor they must have felt that it was far more suited for its intended use than the Bar-B-Que style that they were building.
The relevancy of these facts will become more clear when we discuss the underhanded methods that would later be used to obtain a trademark on the front grill of the jeep by the Jeep Corporation (Willy's successor - and DaimlerChrysler's predecessor).
...
The Federal Trade Commission (FTC) stepped in, in 1943, and filed suit against WILLYS-OVERLAND with the result being that in 1948, WILLYS-OVERLAND was issued a Court Order To Cease and Desist from: Representing, directly or by implication, that respondent Willys-Overland Motors, Inc., either acting alone or in cooperation or collaboration with the United States Army or with any other agency or party, created or designed th automotive vehicle known as the Jeep; provided, however, that this order shall not prohibit respondents from representing that said respondent participated in and contributed to the development and perfecting of said vehicle.
