I have a 1972 Duster with the '72 K-member, but the later ('74) suspension/brake components. which year application aftermarket anti sway bar kit would I need to use?Tom

I believe you will need the early sway bar as the 73-up one goes through the K I believe. I would talk to Dave at Hellwig...he will give you the straight scoop and they make a real nice piece!! He's a member over at FABO and has helped me a couple times. His user name is [Email]Dave@Hellwig[/Email]

Edit: 55906 is the part # for the tubular bar for 67-72 a-bodies as per Dave. HTH
