thank you for responding mass-n-trash, I don't have rear windiw but do have oem windshield, the oem mirror looks like ill be looking up. aftermarket has like 3 or 4 inch extension didn't no which way to goJust something to think about, but I had a rear view mirror on mine with the OEM rear window. The mirror was worthless with the distortion through the window so I went with side mirrors. I found these to be far more functional.
