Looks like we have several very good correct restoration choices. Nice attention to detail in the photos supplied. I my self have done both A/C and Non A/C. Mine however are more clean up glass bead painted items only and reassemble. I like to try to save the original finishes with products like Rust Rescue or vinegar and water solution followed by a baking soda rinse. Still look good after cleaning however not that fresh just completed factory look.
