I had one in a fj40 (vintage air), does that count? If so yes install one if you have hot weather in your region. I like the idea of having the creature comforts. I would recommend putting insulation on the the floor and firewall as high as you can to help stabilize the engine and noise. However, I removed it since I left it topless. Even though I removed it I went ahead swapped in the right motor mount from fj60 that has the bracketry for an a/c. I compressor. I also installed factory powersteering using a 4x4 toyota truck as a donor. It just makes it more enjoyable to drive.
