The new Northern Lights S3C panel is p/n 22-91216.  The older version was 22-91211. The 22-91211 is the panel in most of the current parts books.

Here is a parts breakdown of the new 22-91216 panel: 22-91216 panel Parts breakdown.  Please be aware that the gauge bezels do NOT come with the gauge.  They are a separate part number.

The only way to determine which panel the customer has is by looking at the back of the gauge.
