Now, do us another favor. On your new engine. Right up at the front, in between the drivers side head and the injection pump, there is a nice flat area that has a bunch of numbers on it. See if you can clean it off and read the numbers or take a picture, and post those up here. That will let us know what the engine is supposed to be internally. If we have this info, we can guide you to which flex plate you will need too.
