I'm reinstalling the flywheel on my engine (okay, it's an SVX engine,
but it is still in my Vanagon) and realized that...unfortunately, I'm
going to need some way to hold the flywheel in place while I torque up
the bolts.

In the Bentley they show a nifty VW "tool" VW 215C that looks like it
clips on to the teeth, wrapping around the stud for the starter motor.

So, where to I get one? Or do folks have some other suggestions on how
to keep the flywheel from turning while torquing and simultaneously
not damaging it?
