I have removed ours twice.

Our bolts use a 17mm wrench.

I use a combo box/open flat wrench. Remove the two front bolts, which after breaking torque, I was able to unscrew by hand.

The rear ones require pulling out the track and then use the box/open ends as needed to break the torque. Once part way out, I tipped the washer toward the outside wall allowing further access for my arm and hand to unscrew.
