First Gen Camaro Full Frame

[Vicinity]

I've been doing some research, do they still require a lot of fab to make work with the body? The latest posts I've found are from a few years ago, figured by now someone would have figured out a way to make it "bolt up" (or weld) so to speak?

I really like the idea of working everything out on a separate frame, then mating the body at a later day, on top of the better structure it provides to the body, reducing flex, and so on.
