Does anyone know what tool would be the best to use to remove the headrest's on a 91 camaro?

 

What works good is a flat piece of metal such as a hack saw blade or something bendable and thin. Lift the head rest all the way up and drop it down a half inch and push the piece of metal down the center of the support and it will push the clip closed for you can pull it out. How it works is there is 2 holes in the support and a piece of metal that pushes outwards and when the head rest is pulled high enough it enters the hole and locks it to where it is unable to go any higher.
