Front inner right - plug and seam welded

Rear right inner and B pillar - plug welded

Inner sills paint with 2 coats of POR15

Prior to final welding - clamped in place

Some good progress to report. The inner sills on the right side are now almost complete. The B Pillar on the right side is installed.  I think I've managed to get everything lined up within 1mm of what the diagram I have states.....pretty happy to be honest given that I didn't have any reference points of note outside of the original A pillar that has been maintained.  Time will tell how good my measuring is!
