Yes you put head lining in After windscreen. You need bows for the back of the van as well. If you are doing a ute you put the hood lining In before the rear window. Unsure about what you mean about cover moulds but I'd you mean pinch weld then yes that goes on after hood lining or rather during installing it. There is also a vinyl strip which goes across the inside of the windscreen and two pillars which go from the dash up to the top of the windscreen on each side near side windows if you are still unsure I can take pics of all those things

Cheers
