Help locating Generac Textured Tan Paint

Hi! I have a pre-2008 Generac 16 KW generator. I had to preplace one of the enclosure panels due to corrosion. The paint on the original enclosure is Generac Textured Compartment Tan. While Generac sells small (6 oz.) touch cans of this paint, they are very expensive, and I would need multiple cans. I'm hoping that someone might know of an alternate close match to the Generac Textured tan paint. It doesn't have to be an exact match since it's the over door only. I really don't want to paint the entire enclosure if I can help it. Any help would be appreciated.
