Ready to pull the trigger on rear sway bar set up 70 Dart, 8 3|4 axle....
I noticed the cheap hardware on a Addco front bar , once
Hey if you like it go for it, but then why ask for advice?
Both the Hellwig and Hotchkis bars are high quality bars, with high quality hardware, detailed instructions, and good available support. At least they used to be, I've heard Hotchkis has been a bit hit-and-miss in the support department since they relocated. But honestly they have step by step, detailed pictures in their instructions that cover pretty much anything you could run into.
I personally wouldn't waste my time with Addco, or buying new hardware or modifying stuff because the hardware that came with the kit is cheap/ill fitting. There's plenty of threads here describing Addco installs and the extra work, parts, time required. Yeah, they're cheaper, and it's pretty obvious why.
