SMALL BLOCK Rocker Hold Downs - Factory Style 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.
