In the day, you could have bought the factory wood-grain vinyl across the dealership parts counters. The factory parts book would tell the parts counter people which factory part number to order.
If you want to look up the factory information, there are copies of the factory parts books on the Tom Collins site that may help you. Suspect knowing the part numbers wont help, and you may need some time to find the overlay in the books. https://oljeep.com/edge_parts_man.html
Today, nothing like the parts counter source exists anymore. I believe your only option is to look at what aftermarket wood overlays are available and pick the one you like or which subjectively matches best.
This has been discussed many times here and at FSJnetwork. Suggest you search and read old posts. https://www.bing.com/search?q=site%3Aifsja.org+woodgrain+wood+overlay+v inyl
Note the factory calls this "woodgrain overlay" but maybe not called that in modern parlance everywhere.
