Dealer service guy said ACDelco #8-5800 Universal refills can be cut-to-fit the SSR wiper.
I clean the blades a lot and use an old emery board lightly on the leading edge occasionally. RainX or waxing the windshield helps tremendously too!
Did the 2006 model have different wiper arms?, I dont know what the problem is. Sounds like someone is replacing the whole plumbing with arm just to get new blades?
