A question that I am often asked is:
“Is the spoiler on a Spoiler/Spoiler II the same as a Mustang or Cougar spoiler?” It is a reasonable question since to the casual observer they appear identical. However, they are not.
The basic shape of the two spoilers is very similar but the two are not the same. The quickest way to tell the difference is to simply look at the pedestals. If you are looking at a spoiler with an adjustable pedestal it is for a Mustang or a Cougar. If the pedestal is fixed and not adjustable it is for the Cyclone Spoiler/Spoiler II.
The next question is:
“Since they look very similar can I use the more common and less expensive Mustang/Cougar spoiler until I can find a correct spoiler for my car?” Although technically you can, but the result will not be cheaper or easier.
If you put an incorrect spoiler on your Cale Yarborough or Dan Gurney car the holes you drill in your trunk will not work for the correct spoiler. The holes will not just be in the skin of the trunk but they will also be in the inside bracing. This means a lot of patch work later or or more than likely, a new trunk is in order!
Here are the dimensional differences.
Cyclone Spoiler/Spoiler II dimensions:
The pedestals are approximately 34″ from center to center.
The overall length of the spoiler from tip to tip is approximately 61″.
Cougar/Mustang spoiler dimensions:
The pedestals are approximately 36″ from center to center.
The overall length of the spoiler from tip to tip is approximately 58″.
