Rear window

I’m owner of an Lotus Exige, and I am in search with a complete rear window, with openings allowing the cooling of the engine. Do you know where I can find this, or who can tell me this information ? Thanks ?

why would you want this…the engine vents off the top of the engine cover…just try putting your hand over it to see how good this is and must be even better with the air flow at speed through the front roof intake…I really would want any of this hot air and probably a few nasty engine fumes being pulled into the cockpit.
