I'd buy Original saleen if I were you. Yeah they need a lot of prep work, but when prep is done right, it will fit very nice. The reason why they are sometimes warped is because its like you have to put them out in the sun to soften up and set them up where they are even and they aren't being pulled or sagging anywhere. Then I'd prep it as is, so that it would hold that position. Once that urethane primer goes on, it stiffens the urethane it it will pretty much stay where you set it. if you prep it when its all ****-eyed, then that is what you get for the finish. As far as the 281 wings, maybe they have bum batches. Ive had Original 281 and 351 wings and they fit flawlessly. I think the 4 bolt saleen wings (earlier style) were made better. Its almost like you have to go to saleen to pick good parts. When they are in the warehouse so long and shipped they sometime settle awkwardly and that is where you get the waves....but again Saleen parts are still going to be better than plastic parts. They are durable. You get into a fender-bender, that saleen front and rear bumper is going to hold up and you will only need re-paint. Good Prep Good prep Good prep is how you get it right.
