Several sets A body headers

Fourth set is also small block tri-wye set up. I was told the were in a 74 duster 360.?.? They look a lot like a set a friend has in his small block ram charger 4 X4. Look at the pics these were chrome. They are heavy gauge, the flange is under 3/8 but over 5/16. There is a dent in one primary. $150 obro shipping is on you
