My sway bars are disconected....What is the point I can't tell? what does this do?What size would I need and what is the diff in sizes I have a 2.8l 3rd gen 1987... do these change for the 3.1/3.4/3.8/5.0/5.7 so on?

Are they removed or disconnected? They keep the car from leaning and scraping the door handles on the ground when making fast turns. They are different depending on engine weight and suspension set up. You can pick them up at a salvage yard.

My sway bars were broken and I could really tell. They are currently fine.
