LCA Correct OEM Color - 67 Cuda

Would appreciate comment from anyone who has experience with getting the lower control arm paint color OEM correct, or close. For years I have always painted them to match the K Member. It is my understanding they should be a yellow or gold color since they came from the factory bare with some cosmoline sprayed on to slow down the rust. Eastwood has a gold cad spray, and I'm sure there must be others. Thanks in advance.
