Clips are 19 cents when you pick it out of the bin at your local hardware store.----When a shop identifies the part you need.----Orders it.---Part is retrieved from an expensive warehouse and shipped to you it is a $7.00 part.---And I do not believe anyone is making a lot of money on that item.
Got some clips at Ace today. 3/16 seem to be close to original. Snapped it on and couldn't pry it off with a screwdriver so I should be good to go. 17 cents so I stocked up.
