wbt56 - gday i am in the same situation as XA Fairmont but am leaning towards an lsd as well
i have an 302 windsor auto in a xw with the stock borgy 2.93 single spinner
what would i need to find to get everything, cn i rip a centre out of a VL or 80's skyline as i think they have 3.45 and 3.7s????
You would have to get a hemisphere built. You can use the gears out of said car, but any LSD will be 28 spline axles, and you should have 25 spline. It is not too difficult. Be wary of going so low if you do any highway work. Even 3.45 will see you at 2860rpm plus converter losses, so about 3000-3100 at 100km/h.
