I have a stock front sway bar on my 69 charger. I want to put a rear sway bar on it, does it matter what size rear bar I put on it. There are lots of rear sway bars out there and everyone seems to have different size rear bars, 7/8,3/4,and 1". I was looking at the summit rear sway bar but its 1", is this bar to big to use with the stock front sway bar ??
