I did a search, but could not find an answer to my question. The front bumper on my car sits about 3/8" too low, at least in my opinion, for proper alignment with the hood/fenders. The slots in the bottom brackets that attach to the frame do not appear to allow any more upward movement of the bumper. Since the bumper, grilles, header panel, etc. all seem to be connected, how does one raise the overall position of the bumper? What all needs to be loosened, besides the four lower bracket bolts, in order to reposition the bumper? Thanks in advance for any help, this forum is great!
