I finally discovered that I could get replacement "wide" wiper blades from my local CarQuest, Prairie Grove Auto. CarQuest # 752-200 made by TRICO. They are considered "Heavy Duty." Needless to say, I ordered them the other day and installed them today. YEAH!
Posted are pics of the base of the Driver's wiper arm, close-up of the old clips reused on the new blade, close-up of the wiper blade mount, and of the new wiper blade.
The stainless steel strips that were part of the new refill had clips that would not engage the old stainless steel wiper frames that I needed to reuse in order to reattach the blades to the wiper arms. So I decided to reuse the strips and clips from the old wiper refills with the rubber from the new refill. The frames may be dirty and ugly, but they work! Because they tend to collect leaves and junk between them and the windshield, I am using little blocks of foam to hold the arms out and hence the blades away from the glass. This will prevent the accumulation of crap on them.
