66 C10 leaking cab

I need some waterproofing tips for my 66. When it rains I get water coming in from under the dash, mostly in the center area but on the sides too. I can't tell where its coming from since I'm driving when it happens.

The center could be the windshield wiper motor. The sides might be rust.

Exactly. No one on here can tell you where a leak is.

It could be leaking from the roof seam.
