I have a 03 Monte Carlo SS it has the wing on the back. I was wondering if any of you guys could know were i could get a Spoiler for it and how much it would cost for one like on the newer models.

 

ebay,junck yards, online stores like zz preformance might have them.
but honestly i think Ebay is the best prices i have seen for them and they are not colored so you have to paint to match but htis means you have one that will look right on the car.
Junck yards would be the next choice. im sure some where aroudn you they have one that will ahve monte carlos in it. this body style gose from 01-04 for the front end and 05 for the every thing but the front head lights. But i belive the rear end and intereior is the same as our years cars.

 

are you saying that you have the flat or surf board spoiler and would like to replace it with a nascar spoiler? your best bet is to pick up a 2006+ spoiler because they use the existing bolt holes and you would have to fill them in like you would is you got the 2000-2005 nascar spoiler.
