Currently restoring a 31 Dodge Cabriolet and need paint formulas for the following colors:Arabian Mocha Stone Brown (Ditzler IM 1057) and Brazillian Brown (Ditzler IM 874) Does anyone have formulas for these colors with current paint suppliers???

All auto paint companies have the formulae for colors back to the 1920s or earlier.

Ask your favorite supplier. They will not have them, but can ask head office and get them within 24 hours.

Old formula cards will not work, all paint companies reformulate their paints every few years as they develop new chemistry. You need to get the up to date information.
