I don't think I've ever seen a '98 PSD. I used to be a truck mech. for a construction company years ago. They had a large fleet of F-Series trucks from all walks of life. With the exception of 3 maintenance trucks, there were very few diesels. The only '98 F-250 they had was a gasser. It was weird looking: it had F-250 tags, but it looked like an F-150 body with a beefy suspension & the engine was a 5.4l. In all my years of interest with Ford diesels, I don't think I ever once saw a '98 F-250 PSD. Can anyone show me some pics?
