yeh, I have the headliner and all the trim but I've removed it all. The headliner is in the normal saggy state and since we might be looking at it every night when laying on our backs I wanted to replace it with something better and also something that wouldn't let a litre of condensation form every day. The headliner just lets it form behind and this runs into the internal gutter and then right onto my right leg every time I brake. When I accelerate it just tinkles out down the rear quarter lights. And a litre is no exaggeration !
Thanks for all your help guys especially bagder, errol and red. This is all good, and great info. I'd love to see what you've done if you can post photos or your linings. I'm not doing this yet as its way down the "to do" list but this is all part of the plan.
