Hello all, new here. I inherited a 88 gmc c1500 sle reg. Cab short bed recently. Has reg bed not a stepside. Planning on doing a leaf flip. Tow package removed and no spare tire it sits at 34 3/4 inches to rear fender. Question1 how much higher will it raise after bumper is removed and roll pan installed. Has chrome diamond plated top style bumper, not sure if its original. I know it drops 6". Measured for the flip and axle to frame would be less than 3" dont want to c notch if possible. Has 235/75 r15 wheels and tires. Worried the flip would bring fender too close to this size tire. Any help would be awesome.
