OneStopRestoration's Special Orange 69 Chevelle 300 Deluxe Coupe

[Mr70]

I actually used that same carpet tack idea to do the same on my 72 SS Chevelle back in high school.The carpet was pillowing badly after my cousin used it & left all my windows open overnight during a heavy rain storm.We tried hair dryers etc,but nothing worked.
Drilled holes through the carpet into the floor,and Voila!,it worked.
