1968 QQ1 blue paint formula

Looking for advice on a paint formula for 1968 QQ1 blue. The Dart is ready for paint but the body shop hasn't been able to find the right color. Everything they've tried is too light and looks like B5.(I have not seen it in person...just going by what I'm told at this point) A sprayout was done in 2014ish and the paint matched an untouched section of the A-pillar that had been covered by weatherstripping. That paint line has been discontinued. The bodyshop has done sprayouts of PPG, Nason, Dupont, Shopline and Exalta. Nothing has been correct.

I was just sent these pictures. They sprayed the hood yesterday in order to see a larger area to compare. The sprayout sitting on the hood is the one from 2014ish that is no longer made. I know it's hard to tell from a picture on the computer but any help would be appreciated!
