I've read a bunch of posts about sway bars, but I just can't put it all together. I'm putting my 68 SS 396 back together and I'm trying to understand the different sway bar options. I am not really upgrading anything other than going with poly bushings. My car came stock with the 11/16" sway bar. From what I've read I should get a bigger one. Most posts I've read suggest a 1" solid. It looks to me like the ADDCO has a different geometry than the stock one. The Helwig looks like the stock shape. Both of these are ~ $120. The Hotchkis 1 1/8" hollow is said to be like a 1" but costs an extra hundred bucks. So can someone explain the advantages/disadvantages of these different bars?
