The argent silver codes are DX-8555 (wheels) for non-textured and DNA-8575 (grilles) for textured. These are 1971 Ditzler paint codes. 1970 codes and colors are different. I do not have them. I believe the black is code 9000. You will have to check the black. I am only sure of the silvers. There is an epoxy made for the repair of you part. The paint supplier in your area will have it. Unless your part is reproduction it is NOT abs plastic. Make sure your supplier knows you have an injection molded part. I will try to find my 70 codes. I gave you the 71's so your supplier knows what they look like as far as prefixes. They may have the 70 codes.
