What temp for burnt ends?

[cmayna]

I'm planning to cube up some boneless beef short ribs into some burnt ends with the help of my Weber 22 grill using an indirect heat method (lowNslow).  I assume a good 90 - 120 minutes on the grate then mop and foil over for another 60+ minutes.   What temp would you run at and what IT temp would you pull it at before mopping?
