My comment was not as precise as it should have been. When I suggested chartreuse for the color, I should have suggested that it would be neon or florescent chartreuse.
This is one I built many years ago and is the color I believe the Menard's are.
The Menard's cars have traditionally been more of a chartreuse instead of a neon yellow. I will see this car in May and will know for certain, but based on what I have seen in the past, chartreuse is the way I would go.
