Hard-top trim piece is cut/trimmed for Conv. That's how it was done at the factory. There is a faint line on the backside of the HT trim piece indicating where to cut/trim. However, the '70 is unique in that it has a different screw hole location than the other years. I used a non-'70 HT pair of "A" pillar trim pieces, cut them for my Conv, and drilled a new hole in the "A" pillar to attach the trim.
