The left side door was not in too bad of shape, so I was able to re install it to double check fit & gaps prior to brazing new panels in place. Gaps were not perfect, but close enough.
My apologies for being a little disorganized with the photos & narrative. I took photos with my phone a year & half ago for my own record. Now I'm having a little trouble sorting them out . Hopefully, I'll get better at it as I go. As an example, I was certain I had a photo of the left door fitted prior brazing , but now can't find it.
