Are there supposed to be screws in these holes ? Was there a gasket in this joint? I cannot tell. The entire joint is rusted pretty bad. I was planning on cleaning it out real good with a wire wheel, neutralize the rust, then weld the whole length of it to keep it from rusting again.
Anyone have any experience with this joint that would like to chime in ? | | | | | Joined: Jan 2008 Posts: 4,962 'Bolter | | 'Bolter Joined: Jan 2008 Posts: 4,962 | There are holes to let the water out on each side near the rounded portion of the rear of the cab. Dirt getting in the pocket there caused the corners to rot out. I think originally the holes were shaped like a small louver. | | | | | Joined: Feb 2006 Posts: 649 'Bolter | | 'Bolter Joined: Feb 2006 Posts: 649 | 49 chevyman, from what I can tell it appears that the upper & lower halfs were bolted togeather and then welded. I've attempted to take the bolts out to seperate but it wouldn't come apart due to the welds. As for a seam seal I think it was calked. I'd be a little hesitant about welding due to the distortion/warping. I've always cleaned the seam up and por-15 the area then primed and calked. I've just used bathroom tile calking, it says you can paint over it.

I was not sure what was in there. I have some POR-15 to do the floor with, so I will try the method you describe. Do you just use a automotive seam sealer for the caulk ?
I was worried about warpage from such a long weld too. You would just have to do it a little bit at a time and skip around a lot. | | |
