Recently I was swapping center caps among my 911s. I did not have the special tool that the dealer doesnt sell BTW-
A customer came up with the answer.
Take an allen head wrench, 5/64. Put short end in the center cap hole and bring outer piece of wrench to a 90 degree angle. Take your pliers and pull!
Presto, cap is in your hand, safe and sound.
Hope this helps!
