Can someone let me know which diff gears are suitable for AU2 ute/stationwagon live rear end. I am wanting to fit 4.11's but need to get the right ones. I have seen on Ebay BW75/78, M78 but not being a diff specialist I'm not sure. I know I'd rather get 7.8" crown wheel rather than 7.5"

I have heard that some require additional (extra thick presumably) shimming to work.

Any other tips appreciated

Also, if anybody has a GOOD set of 4.11's I would be interested

TIA
