Product review (5 stars): Easy to install after watching a few videos from Youtube
Easy to install after watching a few videos from Youtube.  Bought this product after the OEM factory installed polymer adjusting kit broke rendering the upper tray nearly obtrusive to the bottom tray.  This was due to the top tray hanging lower at one side than the other resulting in a space limitation in the bottom tray.  As factory has provided this repair/replacement kit, they must also be aware of the complaints of the original polymer installed adjusters.
