Hope this clears up the confusion

Marvin I have copied this info from Roadruuner's rc web site. You can also look up the HPI part number and see in the pic that the wing i'm using comes with the body kit.

For the HPI Mustangs which are not provided with a spoiler:
A lexan spoiler of 16mm total height from trunk deck, and overall chord of 20mm is allowable. All other bodies must use the spoiler included with that specific body set. Built in spoilers may not be enhanced.17508 - 1965 Ford Shelby GT-350
