Was working yesterday on the c-clips for the throwout bearing on our 1956 Low light Karmann Ghia and was struggling for quite some time. Looking around for videos and other tips on how to do it we constantly heard about using screwdrivers or pliers however we could not for the life of us get enough torque to get them on. Our Saving grace was an Allen Wrench or Hex key in other words, with the 90 degree bend it make the job a piece of cake.

Took literally less than a minute when i started using it.
