Has anyone flipped an axle on a 80's Chevy truck B4? I just picked up a 86 C30 dually wheel that I want to lower in the rear. I'm not trying to bag it, just want it lowered to where the rear fenders are maybe an inch below the top of the tires. I have measured the rear springs, it should put me where I need to be if I flip the axle and C notch the frame. Just looking for any advice prior to starting.
