And make a steel bush 9/16" OD x 8mm ID so it fits properly in the shock.
See my how-to thread.

Just visited my local Mini Parts Shop here in QLD
Picked up a Pair of top shock mounts and a pair of Std KYB Shocks
They have the steel bush moulded into each end
So i will turn down a 3/8 bolt to suit

A question
What is the width of the spacer between the shock and top control arm as i want to make a steel spacer

Put flat washers on to get it sitting right, then make a spacer that length.
It is shorter than the dry spacer due to the hydro bump stop bracket on the arm.
You need to drill the bracket out to 8mm also.

Well i must say this easy to do mod made a world of difference
STD KYB Shocks i used
And its rides like a new car
Before it was a bit bouncy
I recommend this mod to anyone with Hydro Suspension
