Lock plate for flywheel bolts for 72-79 Bus and 80-82 AC Vanagon

The is the thin metal lock plate that goes between the flywheel bolts and the flywheel.  It was used only on the type IV engine which was used in the 72-79 VW Bus and the 80-83 2.0l Air Cooled Engine.  The later waterboxer engines did not use this.
