pics of 70 blazer/truck interior

[1970blazin]

I am wondering if anyone has pictures of a stock 1970 blazer or bucket seat pickup interior. Even a picture of a catalog or brochure of when they first came out. I am just wondering what the interior of my blazer looked like when it rolled off the line. Or if anyone knows of a book I could buy that would explain options on the blazers. My sticker in the glove box reads "4784AZ Custom Sport Truck" and "4508AA Dark Blue" how do I decode those options. Any advice appreciated!
