65 Dart Oil Pan

You should be able to use a stock pan (center sump) off and big block in a car. My oil pan was off 68 New Yorker and it fit my 74 Duster. My buddy used a similar pan on his 67 Valiant. No clearence troubles. He has Schumaker mounts with there headers. I don't think you can use their headers though due to you have a narrow A body.
