I just went through this on my Barracuda with Dougs 1 5/8 and a stock pan.
I had to lift the engine ...remove the Torision bar and loosen headers in order to remove oil pan. This for a main seal replacement.
I cant see any way to do it that way on my Dart with 1 7/8 and that pan with the kick out. He might not have to pull engine entirely but damn near !
