67 Cuda Convert weatherstrip help

The A-pillar posts on the vert were reshaped to make them stronger. Top of the windshield frame was altered also. This leaves a void between that and the stainless trim that corrects to contour and appearence. The factory filled that void with a adhesive backed foam. It serves no sealing purpose but can prevent wind noise, insect nests, etc..
Any hardware/home improvement store will have a similar and suitable material in their weatherstrips.
