It is "easy" You have to use the supplied U-bolts, and no more T-bolts, and you have to move the brake line a little to do this.

I have the same problem with springs i put in about 10yrs ago. Still too high. I've heard the Nova front eye brackets could lower it a bit too.. up to 75 Nova.

I took out the second (from the bottom) leaf for a while, but the height change vs. the softness was not worth it. I have bigger wheels in it right now (255/60/15) but would like to go back to the right height. Without that leaf they would rub the fender over speed humps, but the height was not more than 1/2" diff.

Been absent for a while. What cured the Vibe John? Did the new leafs do it? Wasn't the pinion angle change was it? I hope not.
Good to be back. missed you friend!
