thanks. First time doing this. It took me a while (and a few Vcrans) to build up the guts to do it but no turning back now. It was an 80% panel from NPD, paid around $170. so it didn't include the door jamb and upper sail panel areas. After looking at it carefully, I started to see the body lines weren't as crisp as the factory originals (I have heard this from other people too). I'm sure they could be massaged with bondo or whatnot to make them look great but I don't have that kind of skill so I decided to cut the new panel just below the horizontal body line and to the left of the door jamb foldover (look real close at the photo you can see). Also in the back, I cut as close to the edge as possible. So at this point I just laid the new panel on top of the old one (most is still on the vehicle, but I did cut out all the rot). If you were to look behind the new panel, you would see the old panel overlap approx 2-3" all around. Now I plan to cut through, both the new panel, and the old panel (approx 1" away from the body line (keep it close to not cause warpage). This way you butt weld it, and use a thin cutting disk so the gap is minimal. This way you ensure a consistent cut. Just tack as you go every inch or so as you cut with a MIG. Then go back and fill it in little by little. I've never done this before but everything I read, looks like this method will work (I'm sure there are many). I'll post photos when finished. Also, I think just the skin would have got me the same area of metal for less $$$. Probably will do that for the drivers side.
