What is the absolutely correct blue engine paint color for a 74 Duster?
Duplicolor DE1631...? Or VHT Chrysler blue from another thread. Engine paint fades over time so unless you got some overspray on a body part that has not been heat cycled maybe you can get a better match. IIRC even the correct code paint will look wrong on a restoration as everyone is used to the faded OEM paint as the original shade.
