Im stuck with a stem attached to the forks. Top bolt has been removed, 1 side bolt has been removed, 1 side bolt is rounded off. Drilling has no effect what so ever on the bolt. Hacksawing it just destroyed the blade. what now? I can just barely move the stem on the forks but thats using all my strength and it moves slightly - with front wheel and bars installed. The only other thing I can think of is getting a hacksaw blade for metal. help!
