Replaced the original battery tray as it was rusted out. Very good quality black primer coated steel. Was difficult to get in because my old tray was very rusted out, had to use a cutting wheel to remove the old bolts and some pieces of the old tray. Had to use new bolts with some washers for spacing to keep the too-long bolts from rubbing the bottom of the battery. Holds the battery very tightly even without a hold down.
