It's an OE rocco mono wiper. It mounts in the stock location as the Corrado assembly with a g60 wiper motor. One of the existing wiper mount holes indexes the wiper to the correct location. Another hole has to be drilled in the rain tray with a bolt fished up from under the pedal assembly to secure it. The motor is mounted on the opposite side of the rocco assembly. Two (of the three) holes need to be drilled in different places on the assembly to allow the motor to rotate into a different location on the bracket.
The motor has to be re indexed with power off to tell it that the park position is on the passenger side instead of the middle of the windshield. Simply grab some vice grips and protect the threads of wiper mount stem. With the power off move the stem from the middle of the windshield over the passenger side. It moves enough water when washing the windows it will soak the car next to you.
The original rocco wiper arm is being used with a slightly longer aero wiper blade. The Corrado wipers arms have issues with not applying enough down force. They don't wipe a large portion of the glass on the drivers side because of the glass curvature. This cures it and does the work of two blades in one pass.
