Measure length of your wiper blade.
Take that info to your parts store. I used O’Reilly’s. Have a 2015 Precept 35UP. Blades cost about $32 ea.
I keep a spare set since I am afraid you would not be able to get them off the shelf.
I had to order them.
When you change your wiper blades make sure you use the adapter that came with the original set of blades if your are using Trico blades. Their adapter WILL NOT RETAIN BLADE IN THE J HOOK.
