I am looking to add some E-Track to the garage of my Torque 371. I pulled the tie downs that are currently installed and they are just screwed in with 2" self tapping screws. I am not concerned about using the same screws to install the E-Track, but I am concerned about hitting the electrical or tanks that may be located below the floor. Has anyone installed either E-Track or tie downs into the floor? Any recommendations would be greatly appreciated.
