The SD-33 driveline I recently sold had both oil pans included (1x1_Speed_Craig bought the Scout pan for use in the CJ). Unfortunately, I don't think I'd be able to spot it on sight from a picture since it was on the motor when I sold it and I didn't look at it from underneath much (though he might be able to spot it). The DSD oil pan had a very square appearance.
That adapter sounds like an interesting alternative to some of the expensive aftermarket kits that will take you from Texas to NP, though. If you spot a part number on it, let us know. Some of the Scout suppliers may have them.
