Change all of the fluids. Oil, transmission fluid, brake fluid, gasoline.

Replace all of the rubber fuel lines. Failing to do so is just asking for a fire.

If you have access to a borescope (available for relatively cheap on Amazon), look under the engine tin for mouse nests and such.

After that, I'd start looking over stuff like the brakes, maybe squirt some oil into the cylinders, and give it a tune-up.
