I started the installation process today and it took me 4 hours. Inserted passenger side with no problems. I will be fitting it on the driver's side and understand that the holes on the other spacer were drilled incorrectly! Then I had to remove the passenger side, because of course you can't drive with just one. What a waste of my time! Then I see that my returns window closed yesterday, August 27th! I hope they react and do something about it. I shouldn't have time and money for a bug that wasn't found by the QA department. Not a happy customer!
