do anyone know how we can make the rear window open up like a hatch?

you would have to get rid of the rear wiper blade, then do some custom work where there's struts to support the window, make it hinged, blah blah blah.. i mean, its probably pretty simple, but do you really want to spend that much money to make the window pop open? i'd rather have some volk wheels or a JDM body kit.
