I had to fabricate some inner sill plates, the new frame extends into the interior 3/16" on either side.
I made these panels with a 3/16 jog and put a good coating of zinc rich primer on before welding.
This is a section of the panel going in, spot welding with MIG - I am also getting rid of the seam under the rocker panel but upside down welding sucks!

And close to finished on drivers side.
And, still working on the fuel tank modification for the in tank pump module. This is the new pump module mounting ring.
And close up.
