Direct bolt in sway bar aftermarket upgrade 67-72 a body?

i'm using the hotckis hollow front sway bar easy install on a 1970 dart with factory sway bar

Relocating the sway bar tabs isn’t something that everyone would consider “easy”. The hotchkis bar requires welding. I personally don’t think the installation is “hard”, but it’s not just a bolt-on deal. Not everyone has easy access to a welder.
