I replaced the stress-cracked polycarbonate Driver's side Targa vent glass with a genuine glass replacement items from SWS911. The replacement was a little tricky with understanding how to dismantle the catch and the small pin that holds it together. Once I realised what I needed to do it took 30minutes.
I have to say SWS911 was a great person to deal with. The glass was well packaged and exactly as described.
This was the polycarbonate I removed - note the stress cracks. It has annoyed me for a while as it is not as clear as glass and you can see the cracks quite easily
Next you can see the end result
