NZXD 2,328 Posted July 7, 2016 Yes mate 4 times I had the diff apart 3.27 but I am talking about a fmz not a b/w gearbox which has the tooth on the drivers side,here in oz I don't think the fmc ever came out with any rear end gears over 3.00,that's why a 21 tooth is the most you can get for a fmc Yeah I know about the differences in input sides etc. the other issue is whether the gear inside the box has 7 or 8 teeth. From what I have read, an FMX with 3.23 (close to 3.27) ran a 21t, with an internal gear of 8 teeth. 10km out would annoy the shit out of me too.
