THESE ARE NO LONGER AVAILABLE BUT WE DO NOW MAKE SPECIFIC TOOLS FOR EACH PULLEY
Porsche 912 follow this link
12V Beetle or Splitscreen/Baywindow
6V Beetle or Splitscreen/Baywindow
We also do these as kits with correct spanner for each type of pulley .
Now you no longer need to wedge a screwdriver down the back of your dynamo or alternator pulley , works with 6v and 12 volt pulleys , the tool will hold the pulley steady whilst removing or tightening your belt .
Will work on Beetle , Bus and Early Porsche pulleys .
