I tried the vacuum wipers and with the V8 conversion, and a vacuum reservoir, they "sorta" worked.
Then I tried the Chinese ones pictured above and they "sorta" worked.
Last, I tried YJ wipers and they definitely worked, but still required a modification of the wiper arms for clearance, along with welding the stock wiper hole on one side of the windshield frame closed and redrilling it a little further to the passenger side.
This is about as close to a true "bolt-on" as I have ever found.
