I'm just finishing a West Coast and from the picture, that car looks like a West Coast. The interior is certainly WC and the full width roll bar is from a WC. The car looks a little short, but that might be the picture. Other than that, it looks all West Coast to me. I'm not familiar with the stallion, so can't comment on that. You can see more of West Coast cars on their website, which might help.
