Piff 

I recently purchased a couple military surplus bags and am trying to find a way to attach the panniers to my bike on the cheap. There's two d-rings attached to the back of the bag with some thick, well-stitched webbing. Would a couple s-hooks suffice? All I'm planning on doing is bending the s-hook closed around the d-ring. Possibly plasti-dipping the other side that will hang onto the rail of the rack. Will this be fine, or will the pannier jump off the rack? I am also going to run a couple rivets through the bag to attach a bungee cord that will hook the lower part of the rack. If you have a better pannier hook suggestion I'm all ears. Though I'm trying to do this as cheaply as possible.

Oh, and to prevent the pannier hooks from sliding forward and aft I'm going to wrap some zipties on the rack.
