Just an FYI for anyone installing a NB top on a NA.
The top of the rain rail needs to be tucked UNDER the beltline molding.
When I installed my NB top I neglected to do this and the bad storms we had last week left me with a soggy trunk. ::Censor::
I fixed it today though.
Here is a write up and a picture.
