Toyvo,
It was bolted to the floor with the threaded holes, so just he bolt not the nuts. 4-5-6 in KC was pretty sure it wasn't factory since it had the slider track (he has a dozen or so of these trucks and has had more over time). Could it be it was maybe a new option for the slider track? I really have no clue so any help will be appreciated!
