im getting a front and rear wheel alignment in a week..

Trailing arm i cut out wit a electic saw and then hammered it out and chucked the whole trailing arm bush into a fire where i was left with just the exterior ring which you slide over the ES bushing.

For the Mugen ones Beeza has it comes complete...so u dont need to do any of that.

hitting it out with the hammer works well...few good hits and you start to see it move.
