Engine/Transmission (1998.5 - 2002) Billet input BROKE!?

[EBung]

Was showin off a little bit last night and when I hit 2nd gear then the converter locked then something went bang from under the floor board. I thought awww mmmaaaannn! did I just break my output shaft? Must have my input is billet so it must be the output or the intermediate. But wait I still have park so it cant be the output must be the intermediate. Pulled the trans out today removed the converter and I can turn the input with 2 fingers. That tells me it aint connected to nuthin! So now I wait til Monday and call the peaple who built it and see what to do next. I thought billet was an insurance policy but now I dont trust any of it. So much for peace of mind.

Who built it? I have heard of several billet shafts failing. How long on the truck? What mods?
