A friend has a 400 Tranny for a 401/425 Nailhead. The case has a crack near a bolt hole so you get a bare case with the tranny. The crack could be repaired but, you get the extra case anyway. It is missing the tailshaft housing but, I believe it is the same as on any short shaft Turbo 400. $100 and it is in Omaha, NE. Thanks, Brian
