Hi Baza ... welcome and congrats on having a super rare colour, im sure I read somewhere theres only a couple of the energy green ones left ...
When my steering rack went it was sent off for a refurb, so an old rack can certainly be re-used if someone is willing to have it refurbed. There's a 'free stuff' section on here if you want to offer it out or you may get a few quid for it on ebay.
