When I bought my M/H the wiper blades were missing. I asked the PO to put some on, but was never happy with what was fitted, as they would not conform with the screen shape.
I pulled the wiper arms off as they were rusty and ugly, and came up with a solution that seems to work great, and is cost effective, so I thought I would share!
This is what I had...
The fittings on the arms are unusual, so I got some 20" Goodyear Blades from Costco, and they were $8 each.
None of the included adapters worked, so I modded them.
This is how they come... with a Hook style adapter fitted..
This is popped off..
There is a hole in the blade, but the pin fouls the arm, so I removed the Pin...
This allows me to put a small bolt and nyloc nut thru...
I derusted, and painted the arms silver metalic to complete the job!
The new style blades really conform to the screen better that spring style blades!
