So, what you need to fit the OÉ top mounts
12 mm drill bit, I got a staggered drill bit
Drill
Wd40
Top nut on the kW is 19mm
Secure the top mount, drill all the way through, front mount I found starting from the stud facing at you was easiest and the rear, with the studs facing away
Wind off the lower collar on the kW
Undo the top nut
Remove the kW purple anodised cup
The front mount you retain the oe rubber to stop the kW mounting cup from having the ability to move around(it will not affect the ride height)
For ease of installation, wd40 the rubber, fit the kW cup mount
Install back onto the shock and screw on The top nut
The rear top mount, undo the shock top nut, fit into the kW cup and reinstall the top nut
To protect against corrosion, I would also suggest to acf50 the top mounts at this point
