Need Help Finding Parts

[Kisner]

1. Does anyone know where I can purchase "foam tape" that's used in various places on my 68 coupe (specifically between the roof rail and the roof rail weatherstrip retainer)? Home Depot has some foam weatherstrip tape that's very, very close to the dimensions called for in the body manual. Would that work?

2. Lastly, I need some braided cloth to replace the rotted cloth on my door handle to door latch rods inside the door panels. I know the rod slides through it when it moves and I assume it's to deaden any sound or rattles. I thought about using rubber tubing if I can't locate something similar to the original material. Does anyone see any problems with using rubber tubing? Thanks.
