Hello anyone have pictures or instructions on how the rear bumper mounts up. 71 chevelle thanks
Again, assuming 71 is the same-ish setup as a 70:
The two brackets on the bottom of your picture should be the top set. With the double bolt facing the trunk and the other bolt holes bolting to the bumper itself.
The other two are the bottom brackets that bolt to the bumper then bottom of trunk pan.
Pictures of old 70 bumper with brackets:
