I have just started refurbing a set of Rock Shox Quadra 21R forks and the elastomers had dried out I started by digging the top elastomer out no problem then I had to remove the plastic spacer which I couldn't grip or hook out .I then decided to use a small screw which I ground the head down and bonded into a long scewdriver bit holder and then screw it into the plastic spacer and then it just pulled out with ease.
