I have acquired a 69 Dart GT convertible. Being relatively new to Mopars I am trying to get a handle on which parts would be interchangeable to help get this baby back to it's original glory. I am mostly wondering how it may differ as a convertible and/or a GT. Then I suppose there may be some compatibility with Valiants or other Mopars. Or if someone knows of an interchangeability manual that is the one to own. I looked at a few on line but they seem to have mixed reviews. Any help would be greatly appreciated.
