WPL D12 rear window frame

I designed this window frame to be used when having the roof spoiler by the talented MrVein

Since the spoiler removed two of the studs on top, the original window frame couldn't be used anymore. I liked the look so designed this to work in conjunction with it. uses 6 of the original studs to friction/press fit
