SKS U-Stay Kit for Velo 65 Fender

Don't see any mounting screws and/or nuts in the photo. Are they included with the stays?

what is the weight of these without packaging? also are they steel?

are both stays the same length? I was thinking of purchasing one set to use for the back fender for 2 bikes, the front fender is fine without the stay

Package didn't come with nuts and the screws do not fit in the holes they're supposed to go through. Has anyone else had this problem?
