Hello!

I was recently involved in an accident that bent my handlebars.

I have an old Shimano 600 Stem that I'm replacing the handlebar from..

However, I am unsure of what size hex key? I will need to loosen it up and slide the bars out.

My set of hex keys are waaay to short and I cannot properly gauge what elongated size key I will need to buy in order to reach down in there.

Anyone have any ideas of what size I need or tips on how to remove the handle bar?

Thanks!
