I had a real nice 70 deck lid on it without realizing the 71 deck lid is different. Still have the deck lid. I ordered the gull wing and then found another 71 deck lid so I had the right deck lid and wing. Found out later that the early 71's also had go wings as well. I like the gull wing better than the go wing as well.
I like the Gull wings on the Cuda's better. I think they match the flatter trunk better then the Go. That said, I put a Go Wing on the Challenger because it matches the curvier trunk and body lines. I have had a T/A spoiler one of my other Challengers as well, so I wanted something different this time. Anyway, yours looks great!!!
