There may be other AAR/TA owners here that have these codes/part numbers and can help or a registry, as far as the paint color, there may be someone who has duplicated these markings in orange, if all else fails...use street hemi orange, but keep inquiring of the part number's meaning too. If you find out before then, be sure to update us all here of your findings.
