That's part of your problem. I've always seen it with the trannies. 330 '05 had this, with KOP tranny (slots in base plate) attached to the frame with bolts going into slots in the frame.

Also, why would anyone use Lexan as the drive frame? (And don't tell me to see the 2007 design book--that team used a metal frame to support their drive.)
