These are an exact reproduction of the SMALL BLOCK factory style rocker hold down brackets (tabs) and bolts. Great for replacing worn, missing or damaged originals. We even include grade 8 bolts, which are about 20% stronger than the orignals that the factory used. One part number includes 3 narrow brackets and 2 wide ones, enough to do ONE SIDE of the engine. For a complete engine, order a quantity of 2 of these kits. Please note these work for Chrysler/Mopar SMALL BLOCK engines only, (318/340/360, etc). Big Blocks use a different part number.
