2004 common rail Cummins

[1984dually]

Looking at a 2004 truck that had a dash/engine fire. Common rail 5.9/nv5600 dually. 120,000 miles. Want to. Use a gm transmission but getting conflicting info on the rear adapter bolt pattern to the block. Seems they are listed up to 2002. Can anybody confirm the bolt pattern on the rear of the block being the same or different? Thanks

The block itself or the bellhousing adapter?

The industrial versions I've dealt with had a SAE type bellhousing flange that bolted to the 5.9 engine block.
