If this will help someone on one of the Monte Carlo forums had posted this formula for the light blue in his 78 or 79. The number is for PPG and matched a cross reference number I had mixed in the SEM line about 20 years back.
This is an example of the color I used years ago in the SEM product line on the dash, gauge pod and console.
