I have already stripped all interior and body parts of the 09 MKX and I had previously stripped down my 2011 MKX. I added to the 09 mk liftgate, rear bumper, impact bar and tail lights from my 11 mkx and everything fits. Doors seem the same so I am not going to remove them. Now, The only problem I have found is that front does not fit because 2011 Edge has extension and the 2011 radiator support and fenders does not fit. I suppose I should remove the ones from my 2011 MKX and weld them to the 2009 MKX frame. As for the electronics, I plan to move the dashboard with all the wiring, computer bcm and other parts to the 2009 MKX, suggestions?
