Was there a rear spoiler (J81) option from the factory on a '70 Challenger? If so, which style spoiler was it? Was there a front spoiler option also? Thanks
Yes. There was a rear spoiler option called the Go Wing. The Go Wing is 70 and the Gull Wing is 71. There also was the the T/A rear spoiler but it was only available with the T/A. Many people put them on any Challenger also. The front T/A chin spoilers were available as an option on the 70 Challenger.
