Thanks Curt. I have the Resto Pak from GM, that's where the #830 "Commercial Blue" came from. From the scraps I can see on my firewall mine looks a whole lot darker than your Airway Blue. I called GM again and they have nothing to add but they suggested Ken McGee, an autolit vendor from Goderich Ont. Turned out Ken has a GM paint chip sheet from '48 with my blue on it as well as some additional paint codes. For $5.00 I should have it in a couple of days. Thanks again Curt...nice pic of your engine compartment.
