The Stovebolt Site Forums The Shop Area Paint and Body Shop Water Leak Rear of Cab 49 3600

Morning folks
Well I'm getting ever closer to having my 1949 3600 back on the road for June. Finished the floor repairs (ended up a bit of a rush job but whatever, this is a driver for now) and got the fuel tank and seat frame back in the truck yesterday.

I had a new rear window seal installed and it seems good and leak free now, but we had a heckuva rain last night and I found water is coming in from under/inside that "lip" that wraps around the back of the cab; see the attached picture:


Assuming this isn't coming from the rear window seal anymore (never say never I realize, it just seems less likely) any thoughts on the other likely points?

In particular around the outer rear of the cab, there runs a seam that appears to join the upper cab with the lower. Water is sitting in there even though it looks like something that should shed it. Anyone have a thought on that, and IF that is a possibility then how best to seal it? Welding it would be hard to do without affecting the body lines. Seam sealer I suppose if it could tuck up in there well enough but cleaning it out to get a good seal would be tough.

Thanks folks!
