Anyone local to me capable of correcting errors on a 904 race build

So, we got it to a local that I trust ..been in business a long time, like 40 some years I think ..

The sprag was installed backwards, that's where the problem started .. it then broke snap ring on clutch pack, broke the pivot arm on the servo and seized the pump bushing to the convertor hub

couple thousand dollars to fix everything .. yah, cope is a great trans builder all right
Wow. What could "the other side" possibly say to that? I'd be pissed. Thank you for the follow up!
