Hi everyone,
Yes, another noob with a question, hopefully someone can help.

We have three mtn bikes in the family, all were significantly damaged (salt water flooded) during sandy, and i'm in the process of rebuilding/repairing them.

I need a part for my diamondback topanga, having a heck of a time finding a stupid little bolt. It's a retaining bolt for the brake line. They are tektro novela brakes. I've called the local bike shops and they need me to bring the bike in to see what it is???

Any idea where to get this? I've searched ebay and amazon but can't find it.

Any help is greatly appreciated.
