Ignore this post. Found the answer on Pelican parts

Here is what I am referring to
forum And apparently did not use the magic words. But I did try. anyway, I need to know if anyone knows how to install the plastic triangular interior chrome piece for the driver side view mirror. It doesn’t slide over the black adjustment handle as the hole is too small and I don’t want to pull or break it prying it off unless that is the only way. I have been living with a broken one for about 10 years and found an OEM on eBay so I’m trying not to break it putting it on. Any help at all would certainly be appreciated. Thank you GD
