The members on this forum are very generous and patient dealing with things like this. I say this because I see a person asking for help without doing any of the basic research before engaging in a technical discussion. When I see someone struggling with simple symmetric parts and the proper orientation for installation, it’s concerning. Unable to make sense of what’s in front of them and how it functions. Fear of changing anything due to the lack of basic knowledge of how the system operates. That’s when the vehicle should be taken to a mechanic for all repairs (brakes, steering, etc.). As for whoever installed the parts previously, I will give them the benefit of the doubt and assume they were suffering from a visual disturbance known as Reversal of Vision Metamorphopsia (RVM) - objects in the right visual field appear upside down and the left visual field appears tilted or vice versa. Scenario “A” would explain the install.
