Does anyone know what the size of the woodruf key for the alternator pulley. I lost mine and want to know if i can pick one up at a hardware store or if I need go to a bug house specifically.
VW P/N N 12705.1
It's metric-dimensioned, so you may have a hard time finding one in a hardware store. CIP1 says it's 5x5mm, I haven't verified it but I think 3x5mm is more like it.
