i just picked this 98 GMC up this weekend. belltech spindles and c-notch. i'll be changing out the 265's in rear for sure. they are way to big. probably go to a 235/75/15 on the 8" rears since the front has 225/75/15 on 7" fronts. i think that will give it a better, more level stance.
roll pan rear with hidden receiver.
