Sheel-mann Vario Armrest
For those tha have the space and want an armrest, sheel-mann has you covered. Although there isn't enough room to add to Tacoma's, you can add armr4ests for the FJ Cruiser and 4Runners.
Available in matching seat colors and fabrics. This is the "narrow" version of the available armrests.
To install all you need to do is find the two mounting points on the transmission tunnel side of the seat. Feel for the hardware that is just under the material. There will be two spots that match the hole soacing of the armrest.
Cut two small "x" 's on the hardware through the material. Then you will see the hardware. Remove the hardware, place the armrest, then reattach the hardware and tighten down.
