Anything and everything GT6.

As Stoneleigh is only a few weeks away can anyone advise me as to the availability of new, clear door glass for the Mk3 or, failing that, a source of (relatively) unscratched used. I am looking for a clear drivers door glass specifically. I am also after a usable quarterlight RH top swivel 574093. The majority I have come across have all sheared. Can anyone help with either or both of these requests?
Thanks.
Lindsay
