COWL REPLACEMENT QUESTION...

hello all..... Finished some underlying metal work and then mock fit the new upper cowl on the 67 Dart. AMD cowl...
Fits really well except for the upper edges that flow into the A-pillars. Those edges sit pretty high even after clamping the surrounding area. Were there lead seams on these ends originally from factory? Pics of the mock up and ends in question....
To spot weld those edges I would really need to bend the metal down pretty drastically and that just doesn’t seem right. The rest of the cowl sits pretty flush even without clamping, line up holes along the window ledge match up perfectly. It’s just those darn edges. Any ideas or thoughts?

they were on the 66 convertible dart I just did. I actually had to remove the A pillars first then the upper cowl and the the lower one on mine. And yep they had a bunch of lead in that area.
