I picked up an Ortlieb Downtown Commuter bag at an REI Used Gear sale and the only problem with it is the P clips (part number e190?) are missing. I know I can buy the entire QL3 mounting set on OrtliebUSA.com, but I'm trying to find a way to just replace the P Clips. Any suggestions? The only websites I've been able to find that sell just the P clips are in Europe with exorbitant shipping, and Ortlieb customer service stated purchasing the entire mounting bracket replacement was the only option. I'm hoping they're wrong & would appreciate any help.
