Not sure about yours, however some flex plates will only bolt up one way, meaning the bolt hole pattern may be slightly different between each other. The holes may not be equally spaced apart from each other which would only allow the flex plate to lign up one way. Check yours to see if that is the case. As far as what side faces where, the flex plate is usually marked, engine or transmission side. Hope this helps. Good luck, Tommy.

You can use the flex plate from your 97. The are the same. Gt Tommy is right, they only bolt one way b/c the holes are not evenly spaced.

Look at your old motor if your not sure of which way to bolt it.(hopefully you havn't taken it apart yet)

They are internally ballanced. All of them. If the 04 motor is stock then it has the same stock ballance as the 97.
