The Silhouette seat I got to replace my broken driver's seat (as shown in this post) has a different style headrest that is smaller than the Trans Sport one. This normally wouldn't be that big of a deal, but I'm kind of a tall guy, so my head doesn't get any support or protection even when the rest is fully deployed.
I cut open the back of the broken seat, and couldn't really see any sort of release mechanism. How do you remove the headrest without ruining everything?
