I am changing the suspension on my 69 Mach to get better handling. I am putting 1" drop 620 coil springs in the front and 5 leaf mid-eyes in the rear. I am planning on using Midolyne bushings and KYB shocks. Now for the advice part...What are best sway bars, both front and back, that I can get. I have found 1" front and 3/4" rear. Are there bigger ones? Where do I get them? Are there better alternatives to just a standard sway bar in the rear? Any help is appreciated.
