As I removed more rusted areas I found additional areas that needed attention. In this picture you can see another section of rusted metal back up and under the fender. This is a different piece than the one seen in the photo above.
All rusted, thinning, damaged areas were removed then cleaned up for fabrication and welding.
The inner most panel has been replaced as shown in this picture. It was butt welded in place using dozens of tack welds then ground flush.
Additional pieces were fabricated and welded. The piece I am holding is only 1/2 it's original thickness.
This is the B pillar in it's current condition. The fabricated piece you see directly under the fiberglass body has not yet been welded in place. It also requires bonding to the fiberglass. Everything is coming together nicely and I don't expect any big issues. This is tedious work though and I suspect all 4 pillars may end up taking most of winter weekends to complete. Check back periodically for updates and thanks for following along.
