Hotchkiss or Helwig rear sway bar?

Sorry I don't have an answer for your question , but I have another sway bar question,I have a 69 Dart, with a 74 k member that did not have a factory sway bar, who makes one that will install on non factory set up like mine?

Hellwig fits, if you have the car up on ramps, it will take about 2 hrs to install with basic hand tools and a drill.

I bought front and rears off Amazon for around 300 bucks shipped, alot cheaper than Summit.
