This is a remedy available both by original equipment makers and the aftermarket on other cars, but needed badly for our MGs.
Made of tough but flexible black plastic with UV inhibitors for long life. Installs by removing your head rest and simply sliding on for a friction fit. No tools required. Guide can also be modified for snap-on installation if your head rest is frozen.
Sold by the pair.
