This is a pair of 91-92 Camaro door ground effect mounting brackets. These BRAND NEW pieces include brackets for both doors. These are very often badly rusted and can be nearly impossible to find in good condition. These brackets are perfect replacements for your original factory pieces and use all the same mounting points. They come complete with speed nuts for the center studs and stainless steel acorn nuts for the end studs so they'll last basically forever. These brackets are made from galvanized steel that has proven to hold up incredibly well to the elements so they'll outlast the original factory pieces. You absolutely will not be disappointed with the quality of these pieces.
