How difficult is it to remove the interior roof lining from EA-ED Falcons without wrecking it?

I believe it's pretty simple. Just take the trim off around the lining and it should clip off.

Yeah, pretty easy to do.
Take off all the cover strips, sunvisors and interior light,
The push in clip things can be a bit of a prick, I used a broad blade knife to pry mine out.
Before you drop the lining down, lay both front seats as flat as you can with them slid forward,
Remove from the car through a back door, takes a bit of manouvering or you can fold the lining slightly without damaging it.

Got the ellerys manual on CD here so yell out if you want their directions for removing/installing the lining.

Cheers for the advice fella's....It sounds pretty straight forward so I'll give it a go.
