Mounting a 4' Firestick on a Crew Cab 01 Tacoma Prerunner

I want to mount my firestick on the back drivers side of the crew cab. How do I get to the cab behind the rear seats ?

 

You fold the seats down? You mean between the cab and truck bed? There's not too much room, if your good you can make a mount and bolt it up. I put longer bolts in the tie down hook of the bed and bolted a bracket onto the thread sticking out.

 

I knew that the seats folded down, I'm trying to figure out how to get behind the lining on the rear wall without tearing it out.
