Express Van file with 4L60 needed.

I have a customer that 5.3 swapped a v6 04 Silverado truck. He converted it a Cable throttle body setup and pinned the ECM. The 1mb Express Van is what we use that will run the IAC valve still. Issue I ran into is all my Express Van files are 4L80 and truck has 4L60, with no like OS I can't segment swap it. Anyone have a work around or a van file that has be swapped? Current OS is 12587811 from 06 Express Van, but I can use any OS from van that will run the IAC. Thanks!

This may work for you. It is not a DBC file though.
