Besides the FE V8 engines, these trucks also came with smaller inline 6 engines and a 302 cubic inch Windsor V8. Aside from the trims listed above, there was also the Ranger XLT and Sport Custom. The Explorer Special and Camper Special were also first introduced during this generation. The Camper Special was made for a slide-in camper in the truck bed.
These trucks are preferred by restorers because they had a simple design and they were known to be very durable. I've seen plenty of these out on the road that have been restored to like-new or even better than new condition.
If you're looking to buy a fifth generation F-Series, I suggest you use the internet, and sites like eBay in particular. There are also hundreds or even thousands of listings for parts on there.
