Fit for all G Body frames. Made from Premium Grade 1/8 (.120) Pickled and oiled steel (HRPO).
Will need a welder, hammer, die grinder and a bench vice. Strongly recommend professional installation.
Keep in mind it is always best to cut less to begin with and grind to exact fit rather than trying to cut to exact dimensions. Use a vise and a hammer to bend the four smaller frame plates until they match the shape of the notch ends.
