When dealing with older trucks, one of things you might find worn out is the seat. Whether it's an old beater workhorse or just an aged truck that has seen better days, chances are the seat material and inner foam have deteriorated. My '62 GMC's original upholstery was worn out. The foam gave out on the driver's side, and once that happened, the vinyl cover had no chance on its own and tore under the pressure of being sat on. The vinyl was so weak that it was also tearing at all the seams and had holes in it.
Because it was very uncomfortable to ride around on the bare seat springs, I knew something had to be done. To fix the situation, I turned to Brothers to find a replacement vinyl seat cover. The company carries a wide variety of covers in various colors and styles for '47-'91 Chevy and GMC pickups and SUVs. Since my truck build is going to be mild, I chose a simple medium gray cover. The cover cost $189.99 and is a direct replacement for the original.
Though the covers I got from Brothers came ready-to-install, there was still a problem of replacing the foam. For that, I turned to the professional help of LB Threads of Long Beach, California. Fourth-generation upholsterer Mike Sutton and his talented crew have the skills to attack any interior that needs fixing or requires extensive customizing. Though they are able to make the covers themselves, going to them with a kit makes for a more cost-effective fix. Also, the simplicity of the job means that it can be done within a day and your truck won't have to be out of commission for long. In my case, I was able to drive my truck to LB Threads in the morning and by the afternoon I was able to drive it back home.
What is In The Box
Here we have the new vinyl seat covers, which we bought from Brothers. Though they have wrinkles in them from being rolled up in a box, they will straighten out with the heat of the sun. The covers also came with a set of clips, hog rings, and hog ring pliers to attach the cover to the seat frame.
Old: Gone, New: On
As you can see, the original seat covers and foam were destroyed with time and use. In order to fix the seat, it needs to come out of the truck. To do so, eight bolts on the base of the seat were removed. Once out of the truck Mike removed the tracks from the seat and separated the cushion from the backrest.

While installing the cover, Jorge noticed there were spot welds in the frame that were poking the new cover. Over time these could tear the new cover, so Jorge covers the area with a thin strip of foam. If you run short on materials you can also eliminate the problem by grinding the welds flat. |

After all of the clips were on, the excess vinyl material can be cut off with a blade. Then, the tracks and backrest can be reattached to complete the seat. |

That way I will be secure in the seat and not slide around during sharp turns. Because my truck never came with seatbelts, there were no holes for the hardware. So Mike measured out the floor and drilled out four holes to secure the belts. |  15a. As you can see, we doubled...  15a.

The Final Word
Since I have no experience replacing foam or installing a seat cover, it was a good idea for me to rely on the experts at LB Threads. The staff did a nice job and had me rolling in no time flat. Brothers' replacement seat cover worked out great and had my seat looking good once again. Though the seat became a little stiff after the install, the foam eventually softened up, improving the overall comfort.
