1. First remove any impeding wires, bolts, screws and or braces from the outside wall and the same to the inside of cab. There should be no interior, wires, or impeding parts or materials that could damage or catch fire.
2. Place filler panel onto the outside of driver and passenger side firewall and check fitment. Take a permanent marker and go along the edge of the filler placing a reference line on the existing firewall. Do the same for both driver and passenger.
3. At this time please make reference to any factory bolt locations you wish to retain. Example: Hood Hinges and mounting brackets along the original firewall or brake booster. Write down the measurements for later reference. (Panels do not come with holes for cab and year diversity)
4. Using a cut off wheel or electric grinder with a cut off disk you can now remove your firewall. Cut inboard roughly ½ inch along the marked reference line. You can use masking tape as a guide for spacing.
5. Having a ½ lip around the existing firewall will allow you to have a slight edge for the new fillers to rest for welding. Clean the perimeter of the old firewall with a grinding disk or some sort of abrasive tool to remove old paint or any rust. You will need nice clean metal for welding.
6. Take both passenger and driver fillers and transfer hood hinge hole location and brake booster location (If desired). Drill holes into the fillers for hood hinges. You can now place the hood hinge brace on both the inside driver and passenger side for re attachment. We suggest welding braces on.
7. Place the filler panel onto the opening until it is lined up nicely with the top edge and outside edge. You can now tack weld the filler panels into place.
8. If you’re happy with placement of the fillers continue to tack weld them by going around the perimeter in 1” inch intervals. (Minimizing Warping) * Now that the fillers are welded you can grind down your welds and prep for bodywork.
