I just got home and I looked in my copy of "Authenticity Guide 1968 Dart and Barracuda Hemi Super Stock" written by Jim Schild & Larry Griffith. This is a VERY GOOD BOOK if your interested in these cars. ( email jschild@hte.net or www.theautoreview.com ) This book shows many of the different part numbers used in these engine IF they were DIFFERENT than the stock 1968 Hemi engine. It does not list a different part number for a oil pan so you could be correct in saying they used a 1968 Hemi pan. Learn something new everyday.

....there is nothing like driving my 1968 Hemi Dart around town and having people looking at you like you're nuts!!
