The Mopar brand stroker windage tray will hit the front of the stock oil pans, even some of the deeper aftermarket oil pans that use a stock Mopar oil pan core to start with I still have some of the billet .250 oil pan spacer that allow you to use a stock windage tray between the spacer and the oil pan with a 4.375 stroker crank with Mopar size rods PM me if interested ($75.00 each plus shipping)
