CSX SD40-3 (EMD version) Questions

I've read that two units (#4050 & #4051) are already complete and roaming the CSX. How many of these rebuilds are scheduled to be done by EMD? Where is the actual work being done? Lastly, any photos of them? I'm wondering how different they'll look from the previous SD40-3's done by CSX.
Thank you for any help.

The work is being done for the SD40-3 units at Wabtec Motive Power in Boise Idaho.
