Thanks for the link.
I just went back out to the garage and threaded the old bolt back into the bar end and started giving it a few good heavy whacks While I had a pair of channel locks on the end.
I just needed to stop being a sissy and need to put some weight behind it.
Ohhhh I misunderstood.
I had the same issue. My solution was to take a short piece of 2x4 and drill a hole in the center. Then I put the old bolt through the hole and threaded it in a bit. Then slide the board up and hit the head of the bolt, it should come right out.
