[76/85 Truck]

Hey all! I used to have an old white bumper on my rig, but I went to the wrecking yard I work at and grabbed a chrome one with those chrome/rubber uprights. My old bumper was lower on the drivers side by about half an inch, so i thought it was just damaged. But when i put the bumper on it was also crooked. So how would I go about raising the drivers side half? I thought about some spacers but that would only work on the corner bracket, correct? Thanks for reading!
