The Wolf

I recently purchased this truck off eBay. It is a very nice and clean truck, and I think the color is great. At first I was told it was a custom paint job, but the previous owner didn't know anything more than that. Upon further review, I discovered that the truck came this color from the factory, and it was called "Aqua". However, the color code (WE5822), was only offered in 1972. This is where I run into an issue... I did find a sticker in the door that states it was altered by Custom Camp Vans & Services in Riverside, CA. Would this group have the ability to order a color from the factory that they no longer make? The shop is no longer in business. Any advice would be great!
