Default Front Spoiler

Will the 73-79 spoiler bolt up to a 71 without a lot of modifications? I need to get as much air through the radiator as possible, and at the same time keep air out from under the car. Thanks. Ron B.

It won't fit, there were major changes to the lower-fender and front end in 1973-up. You need to get the one for pre-73.

GM offered a Lower Radiator Extension that attaches to the stock polypropylene spoiler. It adds about 4 inches to the spoiler and was designed to grab more air for the radiator.


It's made of rubber (truck-mud flap type material) and easily handles obstructions without damage. You can make one yourself if you can get some material, or may be able to find it from GM. I posted a thread on here a while back on this and included the part number I think.

Good luck... GUSTO

Or you could go totally custom. My electric fan rarely turns on after I put this on.

You can grab more air by running without front plate and no headlight shields.....think that combination add's around 80-100 square inches of flow...

CF77: Can you post a better pic of the spoiler? Looks good, I want to see the mounting details. I like the rubber idea. All good spoilers get trashed. The extra inches will make a big diff in cd and cooling.

Taijutsu, I removed the lower valance and then mounted the front spoiler to the mounting holes for the valance. This is a picture of the front scoop without the adjustable lip.



Underside view



This is a lightened picture to show more detail.



It is really low to the ground though, about two inches after I installed the 550 front springs. If you want more pictures let me know.
