Broken 2003 Expedition Coil Bolt

While removing the bolt holding #7 coil on, the 7mm bolt broke. If I understand things correctly, there is a brass insert that can be replaced?? If so what is the procedure? If not what are my options? Thanks. MT

Parts stores sell bolts. The dealer should have parts.
If I understand you correctly the bolt seized in the bushing. You removed the coil try a hardware store for a proper sized bushing. Use channel locks remove the bolt. Use a vise set slightly looser than the bolt spray with P-B blaster. Use a punch to remove the bolt.
