I run the hellwig sway bar on my 64 dart they give you a Bracket that bolts on to the botttom bolt on your front shocks then you drill some holes on your k frame pretty straight forward. My car had a big difference in handling when I added it, I take corners like the rice rockets on my way to work! Another thing that’s over looked if having an engine torque strap on your engine on my slant six it helped a bunch too.
