dart roof skin

The biggest part of the job is the 2 million spot welds to drill out! When I looked at the job I found there are two layers of sheet metal (forming a beam section) plus the roof skin above the doors. Above the rear window there was only one layer plus the roof skin. The rear window part had me worried, but turned out to be no problem. The other concern was did the roof seam overlap the quarter panel? I can't 100% remeber if it did but I think so. Either way it didn't cause much of a problem.
