I am going to install new body mounts on my 84 SS. Four of the body mount holes are enlarged allowing the mounts to fall through. I have the washers to repair the holes but I need the measurements of the frame mounting holes. I don't want to weld on the washers and then put the body back on with the new mounts and not be in alignment. Does anyone have the frame measurements from hole to hole or does anyone have a frame that has all the body mount holes intact that could take some measurements for me.
