The other day I was sitting around and began to think whether or not it'd be possible to remove my seats and then remove the rails and move them back.. bolting the first holes down onto the rear holes and drilling new ones for the back.. this would of course be after removing my half seats in the back, and I'm hoping it would allow my to slide all the way back against the window in my XLT

 

I guess you could, but I don't think you could use the back "holes" for the seat bracket's front mounts, I don't think they line up and seat would be too far back for any comfortable angle on the seat back.

You would need to fabricate new seat belt mounting, as well

 

Ive considered this myself as I'm almost 6'5" and its just not all that comfortable even when they are all the way back but your best bet would be to find longer tracks that allow it go farther back otherwise your moving seat belts and everything else plus it would look really weird.
