Trying to the tool for the bolts that attach the flexplate to the crank in a kombi 2L auto. Does anybody know what size these are? I'm assuming that they are a double-helix Torx bit (12 points?).

Anybody know where I can buy one to suit a 3/8" drive?

Repco, $48 for a set of four, 6, 8, 10 & 12mm, 3/8" drive...
