Apparently the the supplied clip that comes with the extinguisher is weak… going to use the mount from the panel mount use with the seatbelt location!
If you order you will get the new design
I designed this part to mount the element fire extinguisher in the back of the Landcruiser. It’s accessible from the rear hatch. Available in oak tan, grey or black. Mounts into the third row seat belt mount, either side. Includes mounting bolts to mount the clip from element to printed part and a stainless steel bolt to mount to vehicle.
