This is me personally on the matter, I prefer to butt weld my panels for the simple fact that in my mind lapping the panels makes a new place for rust to form, that's my personal take. If you are still going to lap weld, lap the original over the new, and make sure to drill plenty of holes to plug weld. Also be sure to stitch weld up your seam where the panels meet. But think of this, if you were to butt weld your panels you can clamp the patch over the old and use a die grinder to cut off your old panel and you are also cutting the patch to fit all at the same time, then all you have to do is clamp and butt weld the panels back together. You should have no problem welding at the trim line that you want to use and like you said the trim can help hide any faults, but if you work at it you can get it dang near perfect!!! As for the spot welds I use a 5/16 - 1/4 Rota Broach, its pretty much like a spot weld cutter I bought mine from Snap On a few years ago, Blair also makes them. But in a pinch you can drill a pilot hole or just use a punch to center it up. Hope this helps.

I have a patch panel that goes as high as the tape. I am cutting off the entire length because the inner panel is rusted also and there is no way that I would be able to deal with that thru the holes I have cut now. First question - Where should I cut the panel. I'm thinking (dangerous) that I only need to go as high as the body line located just below the trim rivets. I like that area because if I do a less than perfect job, it will be partially hidden by the trim. Second question ( or statement) - I am going to flange and overlap the top seam. Should the new panel lie over the original or should the new panel be tucked under the original? Does it matter? I can get to the entire backside of that seam thru the access panel in the bed and should be able to seam seal it pretty well. Third - any hints/tips on drilling out the spot welds along the bottom? I bought a special drill for them but my first attempt resulted in the bit walking. Should I drill a small pilot hole? Thats all for today. Thanx Rick Schaefer 72 TPI El Camino
