Will fit CCK engines with alternator on same side as starter. The numbers look like it may fit other blocks as well. I am showing a page from a CCK manual that can give you a basic or vague idea of how the kit parts come together. It is not exact but just an illustration that I found that looks similar to what this is supposed to do. You get the parts pictured, not the ones on the parts illustration.
