1974 Chevy Stepside - Sound Off

He applied waterproof caulk around the passenger-side holes.

The same caulk formed an impregnable border around the passenger-side patch panel.

Without a drill available, he used an awl (hole punch) and a hammer to form holes in the patch panel and the toeboard.

Wielding a socket wrench, J.B. tightened the sheetmetal screws that will hold the patch panels in place.

John repeated the same procedures to secure the driver-side patch panel.

Swift application of the remaining Sound Damping Pads occurred next.

J.B. prepared both surfaces with adhesive.

Firm pressure on the wallpaper roller is all he needed to ensure a secure fit of the insulation material atop the passenger-side toeboard.

John repeated the procedure for the driver-side toeboard.

Wherever a seam still existed, J.B. used the supplied silver seam tape.

Despite having to install sheetmetal patch panels on the toeboards, the Chevy's sultry silver lining was installed in less than eight hours. The firewall insulation component won't be installed until after the Vintage Air HVAC system is installed.

Mere minutes later, J.B. had installed the rubber floor mat and the bench seat. Don't worry; these well-worn items are temporary. Stay tuned for the next tech article on J.B.'s Texas Ranch truck in an upcoming issue of CCT.
