Just wondering what everyone is using for a cab on their 825i XUVs. I have the
  1. Non scratch poly windshield
  2. Poly roof, Part # 4030

from when I purchased my 2014 & I'd like to add doors & a back window to this set up. I am thinking about the OPS Rear Cab Panel, Part # BM24561.
It looks to me as if If I may need to purchase a new windshield at least since the door kit as pictured may not work w/ the Poly windshield I have.

Does anyone have experience with this cab kit? If so, your input is appreciated. What are your likes & dislikes about it? Does the cab seal well in the configuration? What cab units has everyone else bought? Thanks...
