What's under the passenger seat of a front entry coach?

[Eric Perplies]

My air operated step well cover board needs to be repaired. The
bearings (looks like a drawer slide mechanism) that keep it running
straight are shot. I pulled the passenger seat today but I am now
faced with the next step which appears to be to remove the metal ??
plate that the passenger seat mount to, above the step well sliding
board.

Has anyone ventured into this area of the coach? Without knowing how
this plate is fastened to the coach I will likely have to pull the
carpeting from this plate to find the fasteners. I hate to pull up the
carpeting in this area because I won't be able to match it.

Does anyone have any tips to remove the passenger seat mounting plate?
Once I get that plate up the repairs should be pretty straight forward.
