Yeah Gene I have seen that and repaired it before. I'm thinking my leak source will probably wind up being somewhere in the corner of the cowl where it wraps around and goes vertical, based on where I am seeing the seepage on the inside of the cab. If all checks out, I'd actually like to put a bird bath hood on to this rig meaning I'd be in that area because I will have to change the vented cowl panel under the wiper arms as those are different with the bird bath hood.
I thought I heard somewhere, that there is an area around that part of the cab that cracked too? I'm hoping that it doesn't wind up being anything to do with the windshield channel area.
Without pulling the windshield strip, what I can see there looks very solid so far.
