Cosmetic cap removal....

[Seph]

Don't know if people are still needed help but when I did mine I used a bolt remover. drilled the centre of the bolt and used a bolt remover with a reverse thread. easily removed and the old caps are still usable.
My colleague and I did it in work on lunch took 10 mins of drilling the centre and then using the extractor

That's the style we used.
