I may have missed some pictures of what is being done, so bear with me, but what is SO wrong?

They cut the floor to put in frame connectors and beefed up the rollcage. Fine, but maybe that will save the body from twisting up. It's getting a fuel cell. Maybe that will keep it from burning to the ground.

It was a race car before and it's a race car now.

I'm not even slightly with runing automotive history but from what I saw in the pictures this car is not being ruined. It's getting ready to race again. It looks like they are doing a pretty decent job.

Yes, it's being changed. Yes it's the rarest of the rare. But it's not like the guy is tubbing it and sending it to Chip Foose to get it all smoothed out and pearl painted.
