Thanks for the tips Pete, and I need to have some of your patience as well (sometimes I tend to rush because I want to complete a mini project in the time I allotted myself for it).
Now on this outer sill the previous repair had this cut-out on the top and when I removed the 4 or so tack welds holding it on I had a pretty good idea at this point that I'll be replacing this sill.
The inner rocker structure looks pretty solid (some surface rust around the top)...but the rest looks in good shape. The outer sill however....
..has a bit too much bondo for my liking (again another rushed insurance job I bet)..
