Wiper motor removal 78 cj5

[aero13118]

Hi, Just bought my first Jeep and already have a lot of good info from this forum , thanks.
I am replacing the wiper motor, linkage, arms etc. I removed the bolt on the ride side of the motor. There are 2 screws on the left, but they do not have hex nuts on them. "Nuts" have no sides, appear to be pressed on? Not sure how to remove them. Any help would be appreciated.

Leave screws alone, remove wiper arms use a rag underneath them by pushing clip also underneath and prying up screwdriver or small pry bar, remove nuts, go inside remove the plastic oval plugs, remove clips #10 from links #9 & #14, pull out thru holes. Sorry now remove screws #5 & #2, remove motor.
