Looks like the engine was neatly installed.

“Ford 289 CID V8, four speed manual transmission, 4WD, power steering, front disc brakes, seat belts, new seats. Solid frame. Body in fair condition. The engine runs strong and has good oil pressure.
Rebuilt front axle with all new bearings, seals, and rebuilt locking hubs. Complete rebuild of rear axle with new locking center section, bearings and seals. New front brakes with new rotors, calipers, wheel bearings and disc pads. New rear brakes, lines and wheel cylinders. New master cylinder. New oil pan and pickup tube/screen, gaskets and seals. Distributor replaced. Just tuned-up including new MSD plug wires. Several coats of bed-liner inside body tub. New alternator.
It needs new seals in the transfer case, the shifter adjusted or replaced (sometimes shifter sticks), and the tires are old.
As-is, no warranty. Due to the age of the tires, it will need to be trailered home if you are going more than one mile. No trades.”
