I noticed that someone is selling new reproduction glass on ebay: http://www.ebay.com.au/itm/Ford-Capri-MkI-Side-and-Rear-Glass-Set-5pc-Clear-/270960286234?pt=AU_Car_Parts_Accessories&hash=item3f167dda1a
 
It seems a bit pricey to me, but I don't know if these are available elsewhere for less.  I've just been saving/buying 2nd hand glass along the way for any emergencies. Is it too much, especially considering you don't get a windscreen with the set?
 
Cheers
Jamie
