The Liberty shafts won't work, the outer spline is different to everything else.
The last of the GD series WRX shafts will work (non STi with R180 diff fitted) if you can find them.
Or you can use the stock Forester shafts and have the inner spline changed to a R180 size. It requires cutting and re-welding.
Or just use a R160 diff, they never break when using 3.9 or 3.54;1 ratio.
