The interior has been stitch welded in all the important areas, the driver side floor and the Destroy or Die brackets have been modified/massaged to fit the bucket seat. I recommend buying a flat bottom seat if you want a plug and play bucket with these brackets, but I'm still glad I went with the seat I did. Most of the front half of the caged is fit and tacked in, just need to finish the driver side door bars and get the anti-intrusion bars mocked up. Hoping to get the cage completely fitted and welded in by the end of June. After that I will be painting the interior and engine bay, then trailering the car home wo start Engine stuff. KMiata swap stuff should be arriving later this month.
I didn't take photos of every step, but you'll get the idea. Hover over the images for descriptions. I've referenced Tom Hamptons blog (LINK) a bunch as it's been the best resource for photos of the installation process of the Advanced Autosports Spec Miata cage. Not a fan of some of the things he decided to do, but either way it's a solid resource and a fun read.
