I put this old American Racing aluminum unit on my 79 Magnum years ago. This was a 1 owner car....me...and from day one, she had a squirm to it on the hiway. Always felt like the back end was light. This is a GT...sway bars front and back too. (The photo shows her after we had to remove the flares due to rust damage).

Bolted on the wing, and a few tweaks to the angle of attack, and all of a sudden the car handled like a dream.

The first blast over 100 mph proved it worked....I ended up with permanent dimples in the trunk lid....lol.

I've since had to scrap my 79, but we kept all the good parts. The wing is going on my son's 78, because, guess what? It handles the same way my 79 first did.
