swaybar question with 11 3/4 brakes

question is probably old to most, but new to me, i have a 69 dart with the 11 3/4 disc and large single piston caliper........and i want to add swaybars to my car, but ive seen it said that this swap interferes with the front bar, my car is a origional no bar car, does anyone have specific experience with this
any advice is greatly appreciated because nothings worse than getting all excited about a new part that dosent work.

use the hellwig or firm feel bar, it uses the shock bolt for the bracket that holds the endlink. you MAY have to swap spindles side to side to put the calipers at the back. they ARE symmetrical.
