I have some major updates and want to share before work slows down for a few weeks while I'm travelling again.
I cleaned up the rear fenders, in preparation to pull them off- seems like there's no better way to access all the heinous rust new the door and provided the only way that I could think of to check for more rust between the outer fender and inner fender.
During that process, I found that the fender also had some sketchy previous repairs. If I can patch the lip and torsion bar access hole in a reasonable way, then I may be able to just replace the sliver near the door, otherwise it's a whole new fender. I'm hoping by the time they need to go back on, I'll have acquired much more metal working skills.
I also found that the factory welds were a little rough in spots. This was under lead and looks to be in an area that hasn't been touched.
