I bought the truck in 1988. A friend had seen it on the wide ocean beach. That was a good enough reason to totally dismantle and strip the hole car. Luckily I found no sand, salt and no unusual rust, but it seemed to be quite knock around. Sadly I had to replace the 230 Tornado and gear-box. A fully reconditioned 250 Ford, C4, Adapter and Willys transfer-case sits very happily on the under-frame, that is gal-dipped. As for family-car and work-truck it carried us (then three) all over North-Queensland for ten years.
Now our Willys-Ute (as we call little trucks here) has it a little easier.
2010 I pulled the body apart again. Repair rust, sand to bare tin, and paint. The brakes, tray and bull-bar needed replacing. But no other mechanicals needed to be done.
There is always something to do. With the shed the paint will still look good in twenty years.
