How to fix? What tools would I need?
There are a lot of BF forum members around you surely someone will know what to do or how to help, if this is an old 520, it will be a lovely rider to build up. Also, this may be worth looking at with a bike shop. You'll need a new headset, and depending on how much tube length is needed you may need to cut down and rethread the steering tube anyway.

It was originally a 27" wheel 126mm rear dropout spaced bike, however this was just before they made 520's with Cantilevers so you just need longer reach caliper brakes or center pulls to make this frame work with 700c wheels. Cool find and worth the build up.
