Hey guys,

Does anyone have a link to a good set of mirror block off plates?
The only ones I could find look too thin and cheap more me.
This is what I found:

Not sure it will help but I bought those same plates and they are just fine for me theyre are made of aluminum so there sturdy and all its doing is covering the mirror mounts
