Hello,
It appears this truck was a soft top FZJ73 in its previous life.
It is not just the front clip. The engine looks like a 1UZ. Axles have five lug nuts, instead of six. The dash is from a newer model 70 Series. Interestingly, it is oak, not gray.
I guess the mechanic sourced a 1UZ engine, perhaps complete with an H151 (?) transmission from a 100/105 Series. Then he acquired the front clip, dash and axles from a 1999-on 70 Series, and put his monster together. And the creature lives, or so it seems.
I have seen 70 Series dashes grafted into Colombian 40 Series, including the steering column.
A creative mechanic... Not my cup of tea, however.
