Im' curious too. It looks like these covers are exactly the same as in my 2012 SR5. I'm interested in how did you remove these pieces - the manual says about some clip to be cut, which later must be be replaced with the new one (for 80 bucks).
I wanted to run a wire down the driver side A pillar, but I did not want to pay 80 bucks every time I take the cover out. :noidea:
I was able to pull the a pillar trim out about 3/4 of an inch to run a mic cable behind it. (2011 SR5). The trim piece popped right back in place. I couldn't completely remove it but didn't try to hard since the air bag was behind it.
