What to seal with?

[Don B.]

Working on an 85 dodge D150
Right now I'm adding factory ac with new parts where needed, and donor parts from other trucks in between. Also converting from an automatic to a 4 on the floor.
I have the dash out, to swap to an ac version.
Anyway when I first got it home it had a water leak down the cowl on the inside of the cab., Driver side. Also pulled the windshield.
And it was upon pulling the windshield I think I found my source. Did I?

My question is about the vertical seam there immediately next to the inner edge of the top of the fender, at the bottom of the windshield channel. I believe that was where my water leak source was. In other places in the cab, the seam sealer was rock hard and falling off in chunks.
I know that would have to be replaced. Would I seal that up with the same seam sealer I'd use a long the inside corner between the cowl and firewall?
I plan on getting the cab the rest of the way anyway and a complete total repaint. I have 1 door and 1 rocker panel to replace. ( Crinkled not due to rust) [/img:fdb5e781f9]

I had typed " gutting" the cab and stupid autocorrect thinks it knows better than me, and changed it to "getting" the cab. Sorry for that.

Well, I would use 3M8609 windshield install urethane.
It is called window weld super fast urethane, The price has tripled since I started using it. I store the unused in freezer till next project.
