Reilly Street-Lynx Adjustment

My Dart's got a Reilly street-lynx set up in the rear and I noticed that the car sits a tad bit lower in the rear than the front. Upon inspection, I noted that I can move the shock mounting bracket to lower hole, which I'm assuming would raise the back of the car a bit. Two questions; if I move the mount, will it raise the car a bit and will I have to worry about the slight change in drive shaft angle?
