Read my post above, the rail doesn't sit up far enough in the in the curved channel to allow the plastic retaining bar to close. Since it's all cheap plastic, if you force it, it will break. The rubbers on the peg brackets are facing the right way. You just can't get the bags to seat down far enough. Hell I could hardly get them off., It looks like the distance between the top of the peg rubber and the main mounting rail is too short. When ou set the bags on the bike there is a 3/4" gap between the rail and the plastic channel that is supposed to rest on it. Just for reference, I am not a noob here, I have had hard bags of one kind or another since 1983. These are far from right. I went the Yamaha route to simplify things, but that might have been a mistake. But too early to tell, i will be calling them shortly.
