Anyone know what wiper blades fit my 2022 Outback, they are 26 and 17 inch, with I think the DENSO Top Hook fitting, not sure about that. I have struggled to find any listed at the major auto stores.

Try Vipa blades. When my OB was just a few months old, it coincided with Subaru UK offering a free winter- check up deal which included a free set of front wiper blades.  I went along to the dealership, they did the check, but as my car was only a few months old they gave me the wiper blades packaged which I kept until they were needed, and fitted them then.  They seem to be identical to the blades that came with the car, and they have been trouble free - very good quality.

For my 2019 OB the serial number for the Vipa blades are:

WT26U 26"/650MM HYBRID BLADE

and

WT17U 17"/430MM HYBRID BLADE

Hope that helps.  Also see link below

Thanks for your reply, the Gen6 OB is different and use top lock fitting, VIPA website specifies the wrong fitting for 2022 cars.
