Keep track of the wires so they can be installed in the new covers in the same locations as the old ones. |  23 Hog rings are used to...  23 Hog rings are used to secure the covers in place.

It's a tight fit, but you want it that way for a clean appearance and an original look. Once the upholstery is fitted tightly over the bun, a series of hog rings holds the cover in place at the bottom of the frame. The rings go through the cover and around the frame to complete the installation of the cover. |  26 Once the upholstery is...  26 Once the upholstery is installed, small holes need to be made in the covers in different places to allow the installation of various components, such as the seat tracks. These holes, carefully punctured with the end of a pair of scissors, are for the seat tracks. |

Although we don't detail the seatback, the reupholstery is basically the same as the bottom. Re-covering the rear-seat bottom and rear-seat back are also similar, though somewhat easier since the back seat in most Mustangs is used little and therefore the frames are usually in much better condition. |  32 The original Torx-head...  32 The original Torx-head hardware is used to rejoin the seatback and bottom. From here, the seat is completed by reinstalling the plastic trim pieces that cover the hinges, as well as a few other small items. |
