I have caps from J Levi SW. They are awesome. Had them on for 2 years and they have not yellowed ONE BIT, even though my old Seibon hood yellowed in less than 6 months. They were around 200 bucks. When installed correctly, you'd be hard pressed to tell that they're caps versus complete replacements.

However, be careful installing.. I was off by just a tiny bit and now I can't use the mirror retract button or else the cap catches on the mechanism. Not a lot. If I shaved off even a mm of the cap, it would be fine. But my 08 mirrors are so tiny I never use that anyway.
