I had the headers in a 65 Dart I was told that was the correct application. It not correct there for the wider A body car. The headers fit but the torsion bars can't be re-installed. If i'am not mistaken the wider A's started in 67 or 68.
I check for a manufactures tag and try to upload pictures today. Sorry about the information I am new to the site and as usual didn't read the rules. Again my apologies
