Weird cab leak

[bfr57]

My 71 has developed a water leak in a weird spot. It's coming in on the left windshield pillar around the seal. Before you go "Duh", it leaks in without any water on windshield, but when there's some on the roof. I notice there is seam sealer around the edges of roof that is cracked, probably factory. Is there a seam under there that could be letting water in and running inside the pillar and finally out?

Yes, there is a seam where the top meets the metal that holds the windshield. If the sealer gets cracked it will let water get inside the cab and show up in a lot of places.
