One idea could be to put together a gift basket of his favorite western movies or TV shows along with some popcorn and other movie snacks. You could also consider getting him a gift card to a streaming service that has a large selection of western movies or even a subscription to a western movie magazine. Another option could be to get him a book about western movie history or some memorabilia like a cowboy hat, bandana, or classic western movie poster. Whatever you choose, I'm sure your grandson will appreciate the thought and effort you put into finding a gift that reflects his interests.
Or you can get him a star map with an important date you share.
