Is my 4L80E the first ever done?

I doubt it. Is there anyone aboard here that might have done it before?

All the wiring and the TCU and SCU boxes are all in, the trans goes in today. I know we'll need to shorten the driveshaft and tweak the cooler lines, but am wondering how the linkage lines up relative to the TH400.

For the 200-4R I was able to get it almost dead on by flipping the factory frame bracket upside down, but I'm hoping that since the 4L80E is derived from the TH400 (in fact the latter was renamed the 3L80 by GM) that they're the same, and it'll just work if I put the bracket back to factory.

But if someone had done this before, I could ask instead of guessing!
