I don't have CD's or PDF's. I only have the 5 Volume books. I could possibly scan a few pages of the books but lately I just haven't had the time. These books are worth the price and can be found also through ebay (Where I got my set) and Amazon.com

Amazon.com: 1978 Ford Truck Repair Shop Manual 5 Volume Set Original plus vans Bronco: Ford: Books

And a couple on ebay.
