Product review (5 stars): Replacement part is superior to the original part
Do not be afraid of this DIY repair.
The instructions should include a link to this video - https://www.youtube.com/watch?v=otUn8eoceBw
if that link doesn't work, just copy cut & paste the item number into YouTube and you will be directed to a easy to follow 15 minute instruction video.  I replaced the adjuster arms while watching the video and the whole job took less than 30 minutes. You will see the immediate difference between the original adjuster arms and how the wheel clips will not break on this new replacement piece.
