Chimaera / Griff Roof Struts Availabilty

[Bluey Green]

Anyone know what the availability of this part is like? It's not coming up on the new TVR parts web search and general web searches are also drawing a blank. Also, if I manage to source some, is it easy to fit yourself? Thanks.

Ah. One of mine is quite tarnished. Wonder if it's possible for them to be refurbed?
