Sorry to be difficult. the V406 is the right color code which is not grabber blue.
The 1971 pantera med blue is not grabber blue it is a darker richer color and almost has a tint of purple in it.
you can look up pantera blue on this webbpage.

the paint chip shown is close. Definitely not grabber blue which is lighter and brighter.
I am looking for a new paint formula for this color.
