I have been working on the car, but most of it isn't really worth posting on here. Stripping paint, mocking things up, planning, etc... But here's some work from today:
Added the braces that tie the rollbar into the c-pillar sail-panel area. These bolt on via the upper seat belt mount and an additional 10mm bolt.
Here's the plate welded to the sail panel to reinforce the area. There's a 10mm nut welded to the back for the additional bolt.
The plates on the rollbar are fixed with a bunch of heavy MIG tacks for now. I'll grind these back and TIG the plates on just before the car is done, in case any thing needs to change.
I also added a couple of braces to the firewall to inner-fender-brace area.
I wasn't satisfied with the way the stiff inner fender brace butted into the weaker cowl area. So these plates will help spread the load.
