Question on drip rail alignment

[bbs]

I temporarily tack welded my gutter rails in place to check roof skin fit. 

Do the rail sections overlap, or butt against each other at the corner?  I've searched for images or videos that show the fit and I don't quite see it.

I was on the wrong track at first with the AMD picture, it shows left and right halves mixed up.  Didn't take long to figure out the shape didn't match.  I also tried overlapping at the corner but that extra thickness offset the roof skin to one side.

With a butt fit, the front has a natural overlap with the A-pillar flange.  But where the two sections meet, there's quite a gap between the vertical of the front section and the vertical of the rear section.

I'm not at this stage yet and I plan on trying to save originals.

The video I watched a while back (detroit muscle challenger) they placed roof skin on, and positioned the pinched drips rails with roof skin in place, then tacked the rails temporarily from underneath to hold position before removing roof skin to weld them in.  If this doesn't help I'm sure others will better guide you shortly.

I saw that video too.  The challenger has rounded window openings and placing the roof skin on helps position the rails.

It's clearer where the rails are positioned on a Cuda, it has a sharper corner over the rear side window.

I tried to use the roof skin to position the drip rails and I cleco pinned the rails to the roof, but the roof skin held the rails at an angle to the inner structure surface and the roof away from the inner structure.  It was easier to use the window corner to align the back section first.

I shifted the top rail back, overlapping the corner, button welded it in, and I think it now looks like all the other drip rail installs.  Like it should.
