BACK PAD INSTALLATION - 3 PIECE
The real key is to use the old parts to locate the holes for the screw that hold these together. Transfer the hardware and start removing the old vinyl. You need to at least salvage the old foam. It can be filled using new foam if chunks are missing. This is rarely the case (more of a seat thing). If you need to deal with some degradation on the passenger and drivers top foam section some silicone can be built up or we can sell you some thin foam sheet. Again, not usually the case. Note: there are cardboard strips that you can harvest off the old vinyl once the foam is removed.
You will start by re-applying these to the new plastic just as you remove. We can provide you with new vinyl and cardboard strips if you need. This applies to the drivers and passenger back sections. You will want to use a very strong contact adhesive to lay the flat section on. I use Weldwood adhesive and shoot it out of a gun. You can get it in cans, that will be the easiest.
Make sure the solvent is flashed off it will cause bubbles. 15 min should be good on a standard day. if colder may be longer (72f). Get help to stretch and press down. You really only get one good shot without a lot of clean up. This is the single most important part you can easily see.
The center section must have the hardware on before assembly so locating the holes and drilling with a 1/6“ bit will get you a good start. Other than the above “hints” it's just gluing the old pads on, gluing vinyl down and stapling. You can get an electric gun at Home Depot for about $40, Use 3/8” deep staples.
Attention to detail without being rushed will be your goal. Plan on an afternoon 4-6 hrs. You may do it in less, but it is time consuming.
