Some of you may already know that I've just had a new hood and headlining put on my cab, well, all seems ok but I don't know if I'm just being paranoid or what, my main concern is that there seems to be more wind noise at lower speeds than I can remember, particularly on the top of the windscreen. My question is this, on the inside at the top of the windscreen there is a panel where the interior light is housed and where the sun visors are, then there is the roof bit, I notice that there seems to be a gap of about 2cm or so between the two, I can't remember if that was always there or if something is missing, maybe a rubber seal or something when the old roof was taken off.

Can someone check their cab for me to see if they have a gap or a seal.
