Got some more done on the vert. Started on the easy stuff and removed the interior windshield trim and found that the visors aren't original to the car.
Then I removed the top frame and the driver side seat belts and all of the brackets and stuff from in front of it. It looks like the added reinforcement and seat pan need attention too.
I'm fairly sure that I'll need to remove the rear torque boxes to be able to get that rocker brace out without cutting it all up. I looked over that Corral reference thread and some other pics, from what I can tell, they had the outer rocker off and spot welded the bottom of that reinforcement from the outer rocker side. So, my plan is to use my air hammer with a spot weld breaker from under the car and see if I can't get both the floor pan and that reinforcement in one shot without damaging that brace too much. Then, when I go to reinstall it, I'm thinking of cutting some access windows to stick my gun through to weld the spotwelds, then re-weld the windows back into place. We'll see how that goes. So, since I'm planning on using the air hammer like that, I needed a clear shot at that seam, that required me to drill all of the rivets and remove the pinch weld brace. Here are a few new shots from under the car to see what I'm dealing with. I'm starting with the driver side and will need to repeat the process on the passenger side, but figure doing one side at a time would be the smartest path to travel....
If you look close enough at this next pic, you can see where some jackass tried to use a floor jack on the floor.... I guess they took the term "floor jack" literally.
The other thing I did (before I removed the pinch weld brace) was I welded in a few supports. I was planning on welding the subframe connectors, but once I got started laying them out I found that they'd interfere with the torque boxes. If I have to go down that path, I don't want to have to do it twice, so I held off on those for now. I'm planning on welding in a few more, mainly a pair that run from the fore-aft pieces down to the transmission tunnel. But I need to get that sound deadener out of there first, so all of that is still on hold for now.
