I'll stop ya right there...

I should have asked earlier...what model of car is this?
in MY car, the front of the seat track is bolted atop a 3"x3" metal crossmember that extends between the center console hump, on my right to the rocker/sill structure (on my left). it is in this cross member I was referring, I don't recommend drilling holes through the floor to the outside, it violates the integrity of the floor and is an entrance for water, dust and rust. Surely you can fine a slip nut that will work, wreckers is your most likely source..
