Previously I thought I could fix the rusted out metal here without removing the roof.
After seeing more rust while working on the quarter panels I knew I had best remove the roof. Luckily I did. I had rust starting to come thru the roof on the passenger side in 2 spots just above the door and windshield. When I removed the lead from where the roof and passenger side quarter panel meet a spot blew out just under the lead about the size of a half dollar coin.
