Tracks, your teen is looking great!
If you were to get a list of all the bits you are missing and phone Mike, at Mike's 914's in Oshawa, he will give you a way better deal then anything you could ever pull off of ebay.
He would probably give you those flaps fo $15 Canadian plus no brokerage or scum hole UPS double dipping on shipping, etc.
BTW, those flaps look broken to me! Where's the tabs to bolt them on the body?Mikes Cell # is 905-922-8987
