I ended up mounting a couple of folding flag mounts on my saddlebag rails. I wanted them mounted on something that is not mounted to the plastic (like my trunk rack). They are not that high, but they won't cause any hairline cracks, either. They do fold out of the way if I need more access to the bags, although they have enough clearance for most stuff I load, since the first gens don't have hinges on the lids.
They were $25 on ebay.
