I'm starting to understand why they used metal. So this time it looked like it was going to work. The smaller ball size was the key. So then when I went to attach it to the OE roof arm bracket, it squeezes the stem to create the snug tight fit so mirror stays put.
It crushed under the slightest turn. I went slow on the second part but same result. I put the metal ball back in and it worked perfectly.
Any other thoughts?
