While I can't get many of the Nova parts in good old Canada I still snag a few.
These are the bolts that attach the bottom of the bumper bracket to the bumper.
The factory bolts were carbon steel and prone to rust.
While not factory correct these 316 Stainless Steel replacements will be better in the long run.
You can see the heads of these when the bumper is on and will look good.
I had done this on the front bumper also.
