I know a couple of people with 4x4 trucks that year, one is even a factory NAPCO conversion from 1965!!! :thumb: it's a pretty staight forward swap, can't remember if there is a difference in frame width between the years? Unless you already have the parts and tools to do this, it would be cheaper to buy an existing 4x4 toyota, or scout, or something like that. If you decide to do this let me know and I can get measurements and info for you :thumb:
