What is the easiest way to remove these broken/seized bolts? This pic isn't from my truck but it's a good illustration of the same problem I'm facing. Actually 2 of the 3 bolts which hold up the front end of the skid plate are like this. The bolt head is sheared off with the remaining threaded portion still stuck in the hole. I recently bought the vehicle and just noticed this now. If I can somehow remove them I will definitely apply some antizseize compound on the new threads, generally it seems a bit rusty in the vicinity. I'm a bit nervous with only the 1 bolt holding up the front of the skid plate.
