82-92 Camaro/Firebird stainless steel inner bumper mounting hardware.  If you live in an area where rust is a problem, your rear inner bumper hardware is likely badly rusted.  Now you can replace it with these VERY nice stainless steel nuts and bolts.  This set includes all the hardware you need for one inner bumper mount so you will need two sets for the complete inner bumper.  (Note:  The bolts, nuts and washers in this kit are all stainless steel, the retainers are not.)
