i have talked to AMD about this issues people are having with the OE quarters and they have told me that there is a newer verison coming out soon that is "suppose to" have the issue resolved.
I do not reccomend Cross Canada Auto Body panels if you can get your hands on AMD panels. The CC AB panels are poorly stamped and show waves on the flat surfaces. This requires a lot of hammer finnishing and filler = $$$$$, if you have it done at a bodyshop.
FYI - any brand of body panel require some fitting, some brands are easier to fit than others.
