While backing out of the garage my driver side mirror got clipped and the top cover broke off and won't clip back on. The dealership is asking for $550 to replace the whole thing and claims you can't just replace the top cover.

It's a 2017 NX 200t in Eminent White Pearl (0085). I found the part online but not sure which color is correct.

Here's a picture (#2 in the diagram) of the cover. https://www.dropbox.com/s/2c93tu0spp...cover.png?dl=0

The part # is 87945-0E060-XX with the last two being the color. I think it's 87945-0E060-A0 but it doesn't say that it's White Pearl so not sure if it's correct. Does anyone know? Thanks!

Here's the link to A0 (https://www.lexuspartsnow.com/parts/...-78010-a0.html) and here's the list of all the options (https://www.lexuspartsnow.com/parts-...0t/mirror.html).
