47-55.1 floor patches

[osaltyone]

My truck is painted and together; since I am on quarantine thought I would work on the floors since someone covered the worst parts w tar and riveted them down.

Wondering if I take these small sections out how much I need to brace and how I would brace if the doors and everything is still in place painted. Any suggestions?

I have both patch panels for the floors and kick panels. Should I just cut out the major rust? On the passengers side I don't think I would really need to remove the whole pan.
