One idea could be to get him tickets to a local or regional pro wrestling event. If that's not possible, you could look for memorabilia or merchandise from his favorite wrestlers (such as t-shirts or action figures). Another fun option could be to create a personalized "pro wrestling championship belt" by getting a replica belt and adding your grandpa's name to it or creating a custom design. Finally, you could consider getting him a subscription to a pro wrestling streaming service so he can watch matches and events from around the world.
Or you can get him a star map with the date when he was born.
