Small update:
Finished the right cab corner, right kick panel patch and lower A pillar patch. Got the right rocker panel fit and welded on. Seems like all I've been doing is weld and grind, weld and grind!
I had noticed that I could see daylight through the floor pinch weld. All of the seam sealer in there has dried up, plus a couple of little rusted areas. So I decided to go ahead and begin shaving it off.
A couple of areas were going to have to get shaved anyway for the body drop so this should make it a little more consistent looking. Not done, but getting there. Welding the inside, grinding off the pinch and planning to weld up the outside.
