(Remember these are items you will need IN ADDITION to the materials posted by Frenzy in his pannier instructions http://www.instructables.com/id/SOC3NSFFRBPY11F/
UPDATED NOTE: I would also recommend going to a local privately owned hardware store rather than a big box. The people will know better where to find what you are looking for and are usually better at problem solving with you than at the big box stores. I also found that the small local hardware store was cheaper overall for the things I needed.
- Length of Bungee (Aproximately 1 foot, but may vary depending on your bike) ( find a bungee lying by the road on your bike ride, or find a simple bungee and cut it. You might be able to find bungee stock lengths at hardware or boating stores. )
- Metal Ring (75 cents each)
Hook ( NOTE: If you are using a hook, Just use an existing hooked bungee and leave the hook on the bungy )
( this depends on what hardware your rack/bike have on them. My wifes bike has hooks at the bottom, so we used rings that slip over the hooks. Mine doesn't have those so I'll probably use hooks on mine to hook over something down there near the axle)
- 2 Coated Retainer Clamps (50 cents each) (sized appropriately for your bungee. I used 1/4" )
- 4 Washers ( 7 cents each)
NOTE: If you use the washers you may need a longer bolt/screw than you originally planned for.
