Just to be sure what is the 6th digit in the VIN? It seems more and more that this is a 1970 Duster that may have an issue on the title. I may be total wrong.
the 6th digit is a 3 and the VIN seq # matched the number on the rad support. I was worried about that too so I made sure to verify. What is funny is that this is the second 73 duster in as many weeks that I've seen with a 71 front clip and tail light panel.
