I added the vinyl upholstery to the base package tray of the 72 Mustang Fastback. This makes for a much cleaner appearance and adds a hint of texture to the rear area of the Mustang fastback. In my previous post, I talked about where I obtained the new package tray board and checked for dry fitment. I took a trip to the local fabric shop (JoAnn Fabrics) and picked up a yard of headliner material (foam) and the marine grade black vinyl. I also picked up a can of Locktite multi-purpose adhesive ($10.00) to glue the upholstery onto the board.
The first step was to lay the board in the vehicle and mark the speaker hole locations. I wanted to precut for the speakers before I added the upholstery. This is easily done by laying the tray in place and opening the trunk. Trace the locations of the speakers onto the tray with a trusty ol’ sharpie marker. Once the holes are marked, cut the speaker holes out of the tray.
After the holes are cut, you’re ready to begin the upholstery process. Lay the package tray in an area you don’t mind getting adhesive overspray onto and lay the headliner foam next to it. Apply an even coat of adhesive to the headliner foam and to the package tray. Let the adhesive set up for approx. 3 minutes and then gently lay the package tray onto the flat headliner foam and apply even pressure. Do NOT try to lay the foam on top of the tray, this will cause air bubbles and make for an ugly finished product!
Once the foam is laid down, trim it approx. 2 inches longer than the tray and fold the corners over onto the back of the tray. Now you’re ready for the vinyl, Cut an adequately oversized piece of vinyl and repeat the adhesive process, let it set up for 3 mins and lay the tray onto the vinyl. Make sure everything remains aligned and fold over the edges and glue. Now you’re ready to clean off your newly upholstered tray and install it into the vehicle.
When adding the speakers, simply cut a small X in the vinyl and lay the speakers into the tray.
