During shipping the bags with mounting hardware got seperated from the flaps. I had a 50/50 chance, but lost when I tried to put the front flaps on with the back flaps hardware. Be advised that the hardware is not the same and after I relaized my error, it was tough getting the parts switched around ( they kept falling down behind the black plastic behind the guard ). Anyway, its a good fit and not hard to do...if you do it right. Hope this helps another do-it-yourselfer down the road.
My hardware was all switched up too, but I recall that the instructions at least vaguely described which hardware is used for which end of the car.
What screwed me up was the clips the screws go into. At a glance, they pretty much looked the same, but the ones in back were shorter than the front ones. As a result, I was trying to get a clip to reach a hole that just wasn't long enough to get there. I was pretty mad about it till I started on the back and realized that the clips back there were just what I needed up front. I always read instructions in advance, but the drawings weren't detailed enough for the difference to show. Bottom line is they are on and look fine. God bless ebay.
