Product review (5 stars): The only FIX to this common problem
I, like many others, attempted a 'fix' of the original plastic adjusters by drilling and installing the rollers with stainless screws / locknuts.  The fix only lasted a couple of months before the screw holes broke completely.  So the fix is only a temporary solution, a waste of time, and waste of ~$8 and a trip to the hardware store.  You're better off to just live without the dishwasher a day or two, order this kit via prime, and do it right the first time.
