Hi all,

I've been searching for ages but cant find the gear ratios for T18 diff,
apparently there is a series 1 and a series 2 which is slightly rarer in aus.
I have herd that the series 1 is 3.9 but I'm not 100% sure. Also is there a
way to find out without pulling the diff apart, some sort of code written on the diff,
the code on the chassis won't really help because the diff has changed cars.

Thanks
