I finally found the right size quick release fastener for the side cover on my WRX. These parts are from a 2008 TTR 125 right side cover... Yamaha part #'s and MSRP: 3FV-28386-00-00 bolt head $12.70 2TK-21757-00-00 nylon washer $0.80 5TJ-21757-00-00 retainer washer $0.47 4XV-2177L-01-00 clip $2.20 You need one of each of the above. Put the nylon washer on the fastener and slide it down so it is under the head. This is to keep the fastener from scratching the plastic or paint. You can see the nylon washer here... Stick the fastener into the side cover hole and then install the retainer washer on the back side so the fastener doesn't fall out. Install the retainer washer with the flaired teeth facing the bike... Now comes the fun part. Remove the bracket from the bike that the old bolt screwed into. You will need to cut or grind the welded nut off the backside of this plate so the new clip will slide over it. You may also need to drill out the hole a little bigger for the quick release fastener to fit through. Then just reinstall the plate on the bike and slide the new clip over the plate. It fits perfect and lines right up with the existing hole. After you are done you may need to adjust the clip by bending it so the quick release fastener grabs it completely. This is a 1/4 turn type fastener, not a threaded bolt, so it needs the proper spring tension to hold. You will know when you have it adjusted right when you put the fastener in and turn it and hear a click. Then just fold down the D-ring and you're off to the races! I am still working on the same setup for the airbox door. This one is too short since the airbox door is thicker than the side cover. This one is 17mm long from under the head to the tip. I think I need a 24mm bolt to do the airbox door. I have one on order, so I will let you know how it fits.
