Had a little bit of time today so played with the patch pieces because before I can replace the firewall brackets, I need to patch the toe-board areas.  I must also take into consideration where my patch will connect with the full floor pan I will be replacing.  So after studying some pictures of a full floor pan, I cut into my two partial floor pans for the pieces I will use to patch.

Used some tape as a guide so I cut as straight as possible:

Other side:

Cleaned-up the edges a bit and decided on focusing on the passenger side first where the rusted-out area was bent up from removing the firewall bracket:

So I used the plasma cutter to trim some of it away so the pan will sit in there better to give me an idea of where to cut next:

The plan for tomorrow is to cut the floor area smaller than the patch panel, then – if time permits, trim the patch panel to fit in the cut-out area.  I should also mention that there are two ways to do this: either lap one piece over the other (easier) or butt them right next to each-other side-by-side (harder).  I want to butt them together which is a little more work and difficult, but should have better results in the long run.
