So I recently bought a 24 Tacoma, (private sale). On Sunday I was cleaning out the back seats of the truck and I went to put my weight on the front passenger backrest. As I did so the rear of the seat lurched forwards and came off of the floor. In looking closer I saw that I was missing the bolt that mount the seat frame to the chassis turning it into an ejector,seat if I were to get into an accident . I searched high and low for it but never found it. I know for a fact the previous owner never took the seats out so I’m scratching my head on how this could have happened….. Factory slacking? Did it back itself out? Kinda stumped. Does anyone know the exact part number I would need? Cheers.
