well that makes sense because obviously it's a 4spd in the datto ute, and it runs sweet in fourth around 100k's

The H165 diff that was used in series 1 & 2 Bluebirds [910] that were originally fitted with either an auto trans or a five speed, had a ratio of 3.9 to 1

If it came from a four door sedan that was originally fitted with a four speed gearbox, then it will be 3.7 to 1 ratio
