16 To work the upholstery over the larger Sport XR bolsters, a section of plastic (trash bags or grocery bags work perfect for this) is placed over each bolster, which allows the upholstery to easily slip over the foam instead of being grabbed by it.
17 As you secure the upholstery to the seat bottom frame, ensure the seat foam is seated over the frame. Looking at the seat bottom from the side, you should clearly see the foam’s edge. If you see or feel the seat frame, the upholstery needs to be pulled back and the foam properly seated.
18 Use a pick tool or scratch awl to locate the seat back adjuster stop and reinstall it as shown. Use a razor blade to carefully cut the required holes for the two pivot pins as well.
19 Moving on to the seatback, the upholstery and foam are completely stripped from the frame just as we did with the seat bottom. Adding TMI’s optional headrest kit is a breeze at this point; simply cut away the burlap at the top of the seatback frame and bolt the headrest adapter into place as shown.
20 Install the new Sport XR foam and upholstery to the seatback following the same steps as previously outlined for the seat bottom. Use a long pick tool or scratch awl through the headrest bracket to locate the headrest guide locations and install the guides.
21 Locate the seatback cover retaining holes and use a large Phillips screwdriver in a twisting motion to cut the upholstery away. Transfer your old retaining clips to the new TMI covers and snap them into place.
22 Before installing TMI’s new full Sport X door panels, a QuietRide Solutions’ WeatherShield kit was added. The WeatherShield kit includes sound dampener strips for the door skin and foil vapor/moisture barriers for the door panel area.
23 The TMI Sport X door panel is a new molded plastic door panel covered in matching materials to complement the Sport X and XR seat upholstery. They fit the Mustang door shell perfectly. Installation requires high-bond adhesive tape and/or upholstery screws with finishing washers. For this installation, tape was used at the top with screws along the bottom edge. You will also need ’65-’66 Pony-style door pull cups, inserts, and mounting brackets to complete the door panel install.
24 We also sourced QuietRide Solutions’ AccoustiShield insulation kits for the floor, trunk, and body areas. Shown here is the floor kit. Each kit is incredibly complete with pre-cut insulation, sound dampening strips, spray adhesive, and foil sealing tape with fully illustrated instructions.
25 The sound dampening strips are applied to the clean bare floor pan first. The strips are pre-cut and labeled for placement; just follow the diagram in the instructions. Place the strips accordingly and then use a roller to firmly press them into place.
26 After the insulation sections have been glued into place, use the included foil tape to fully seal the edges of the insulation to the body and to cover all seams between the insulation sections.
27 With the floor and trunk insulation complete, including a new insulated rear seat divider and insulation under the new vinyl wrapped TMI package tray, the freshly upholstered rear seat and vinyl wrapped quarter trim panels are reinstalled along with new premium cut pile carpet, also from TMI.
28 Once the front carpet is installed along with new speaker kick panels and the original door sills, the new TMI full length console is laid into place. The front of the console wedges nicely under the dash and at the rear we fastened a small bracket inside the console to secure it to the floor pan. The console features large cup holders, a front storage bin, and a rear storage cubby with armrest.
29 The final piece of the interior puzzle, the Sport XR front buckets, are set into place and secured with the original mounting hardware. TMI tells us that later this year you will be able to purchase completely assembled seats, saving the hassle of upholstery installation and dealing with old, cracked, broken, and rusty seat frames.
30 Brian added a few additional touches of his own during the interior upgrade, including fresh paint on the dash, a new Retrosound in-dash stereo with new Pioneer speakers and amplifier, and Lokar window cranks/door handles. A TMI one-piece headliner was installed as well and readers can look forward to a separate installation story on that in an upcoming issue.
