1985 F250 6.9 IDI diesel

1985 F250 6.9 diesel. 4 speed manual 4wd. Its a bit of a project. It runs and drives ok. Decent tires nice wheels. Recent new glow plugs. 4wd works but The front axle u joints are sloppy. Brakes are spongy comes with a new master cylinder. The front fuel tank leaks if you fill it too full. Comes with a new tank. Gooseneck ball in bed. Slip tank with pump. Speedometer doesnt work. Ive had it about a year and noticed a slight drip of coolant under truck. Found out it has a crack in the block next to the starter by the block heater. About 4 inches long. It still runs ok and doesnt overheat. I think its been cracked for awhile. So either fix it or drive it how it is. Or use it for parts. Ive got too many pickups and other projects Id rather work on. Call or text evenings and weekends.
