Finally, a hard to find reproduction of the factory bolts that will allow you to bolt your engine support brackets to the motor mount ears which are cast into the side of your engine block. These have the thin style washers and fine thread just like the factory originals that Chrysler used. And because they are US made from high strength steel, they work great for those high horsepower applications as well. One kit contains six bolt/washer/nut assemblies, enough to do one complete engine (both sides.)
