sway bar question

[fdbdw]

71 c10 LB,
Just put on a new front sway bar, shocks, wheel bearings and new ball joints, after reading a few posts on sway bars I was excited to get it mounted, I have to admit Im a little dissapointed, I dont notice that big of a difference with the sway bar added. the end link and frame bushings are rubber and Im wondering if getting urehtane bushings will make a difference and, If I can find a pick and pull, adding a rear sway bar will help (rear coils on this truck) Ive trippled checked and I know Its mounted correctly. Any opions will be great. ( maybe I was just expecting to much)
