I was also thinking maybe a little hammer and dolly work to make the a pillar better flow into that curve. Then finish with some filler etc. And just do a little build up with the metal to metal on the A pillar toward the roof line onto the top. Or like Mr Jack said and let pop do a little metal filler line there and file down then filler.I think that issue can be overcome with body work. I'm not right there looking at it and might change my mind if I was, but I think I would start with puting a tack weld at the inside corner where the front of the A pillar turns inward for the windshield opening and then hammer and tack weld to get it in alignment. Then I would body work it with metal to metal and then finish with Rage Extreme.
