Congratulations on the purchase of your 1947-1953 Chevy Truck Speaker Grille & Glove Box and thank you for supporting LS Fabrication on our journey. These instructions will help you fit your new billet speaker grille and glove box for a perfect fit and finish. There’s a slight difference from one truck to another, but with some patience and our photos as reference, you’ll have your new billet dash pieces installed in minimal time.

Speaker Grille & Glove Box Install

Installing Supplied Hardware

After opening the box, remove the speaker grille from the packaging and flip it over onto the packaging foam to view the backside. Remove the hardware from the bag located behind the speaker grille and thread in the supplied Allen keys (4) #8 stainless steel studs into the four corners of the speaker grille. Blue Loctite can be applied but isn’t required. Retrieve the (4) #8 stainless steel lock nuts.

Remove the bottom glove box door and flip it over onto a cloth or soft surface to view the backside. Remove the (2) #10 ¼″ stainless pan head screws and fasten the LS stainless steel latch. Also remove the (4) stainless steel #8 3/8″ pan head screws to be used for attaching the hinges.

Speaker Grille Install

Install the billet speaker grille into the original holes — the studs slide into existing holes. Be careful not to scratch your dash. Reach behind and thread on the (4) supplied #8 nuts finger tight. There’s some adjustment available, but wait until the glove box is on to see what’s needed.

1. Mount the hinges. Hold the glove box door open (on your knees if sitting on the seat) and swing the hinges toward the mounting holes. With a Phillips screwdriver, gently thread in the #8 3/8″ stainless screws. Start with the glove box as low as possible before tightening.
2. Test the close. Slowly and carefully close the door, inspecting all painted surfaces — nothing should bind, rub, or touch the dash surfaces. Adjust the hinge up/down, left/right, or in/out if needed. Inspect latch clearance as you close — the stainless latch comes very close and might need door adjustment to clear the top of the dash.

   

3. Align the grille. Once the door closes without binding or rubbing, align the speaker grille to be level with the glove box — move it up/down, left/right for an almost seamless look. There are 8 screws total to adjust glove box placement. After each adjustment, carefully close the glove box again and watch for rubbing or misalignment. Once alignment is right, tighten all hardware and remove fingerprints or tape.

Phantom Billet Dash Install

These instructions will help you fit your new Phantom Billet Dash pieces for a perfect fit and finish. Take your time and use the images as reference. Use the supplied installation templates below:

Hole Template Circle Template

Installing Supplied Hardware

Both Phantom Gauge pieces come with (2) 1″ #8 set screws and (2) flange nuts. Use the supplied Allen key to install the set screws into the back of the Phantom Dash pieces. The gauge piece needs a set screw in the top and middle, while the piece around the light switch needs set screws in the top and bottom. Blue Loctite can be applied but isn’t required.

Installation Templates

1. Verify print size. Measure the 4″ and 6″ scale lines to confirm the print size is correct.
2. Cut out the templates. Carefully cut out installation Template 1 and Template 2.
3. Use Template 1, then Template 2.

Template 1 places a masking tape crosshair on the left gauge so Template 2 aligns perfectly:

1. Align the gauge circle cutouts to the gauge holes.
2. Use a small piece of tape to hold in place.
3. Make horizontal and vertical “crosshairs” through the left gauge — don’t curve the tape, make pieces longer than needed and rip right at the bottom.
4. Verify your crosshair lines are centered — should be ~2.6″ to center for both.
5. You can leave the template on or remove it and just leave the tape.

Template 2 determines hole placement for the Phantom Dash pieces:

1. Attach a small piece of tape to hold the paper and allow adjustment.
2. Align the vertical and horizontal lines perfectly to the tape crosshairs.
3. With the set screws in, confirm the Phantom Dash pieces sit correctly.
4. Drill holes starting with a ¼″ bit. Work up in size and keep checking fitment — don’t go larger than 3/8″. (The steering column may need to drop slightly to drill the bottom center hole on already-completed trucks.)
5. Once holes are complete, use a Q-tip to apply a little paint or copper coat if the dash was already painted.
6. Install the Phantom Dash pieces using the supplied #8 flange nuts — verify final placement before fully tightening.
