rear sway bar?
I have both front and back Hellwig bars on my 72 dart. Awesome product and great customer service. I had ordered them a long time before I actually installed them. By the time I got around to installing them they upgraded a few things on them. They replaced the old style hardware with the new style hardware without hesitation and did not even ask for shipping on them. The car handles great with the bars installed. I can not wait to buy a second pair for my 70 dart.
