What engine is in it? If 3B the ratio is 3.7.
If 4.2 engine, ratio is 4.11.

Your chassis code should tell you.

Are they different to the BJ73 midi. I had a 3b in mine and it is 4.11.

All of the FJ/BJ cruisers came out with 4.11's only there is no such thing as a 3.9 ratio in landcruisers but there is in MQ/GQ you may have your wires crossed.
