On Laramie the existing rear liner is two pieces that is supposed to be split apart and then you reuse the rear part of it. If you don't split the rear liner apart the holes don't really line up. Existing front liner you don't need to touch.

@Evilemokid94 my BigHorn install was slightly different (as follows) than this otherwise excellent Laramie video described:
- Needed to buy
SIX EIGHT extra hex head screws, part # 6510175AA, $1 each, in stock locally
- Did
NOT remove the rear inboard screw clip to shift it forward, since I re-used that mounting point to secure the rear backing piece (see next)
- Used the back half of the rear panel as described in the vid,
but I reinstalled the screw at the inboard position for stability
- Reused a screw clip
off the old front liner for the inboard center hole. Tapped it with a hammer to “lightly smash” it closed a tiny bit so it would stay put.
Other than that the video was spot on, and SUPER helpful. Liners in, took an hour or so.
