This car absolutely came with the dated XT rims painted silver. The spare even has a job# and the silver paint is original. As Charley stated there are no earlier built cars with YJ date rims. I debated this with John Z and many others years ago. If you research, you will find threads just on the wheel /hubcap configuration.
What I am amazed at, is how the rally cap top was mounted onto the dog dish. Who the heck would have taken the time and effort to make this work. For those unaware an XT rim will not accommodate a rally cap which is why the goofy caps were configured.
Here's the original write-up I did on the car....
