Bought an Eaton case off a member here a couple weeks to port it but decided I rather get a whole Eaton instead. The case had two helicoils due to broken bolts. All blower to IC bolt holes were drilled and tapped to allow a larger 6mm allen head bolts from Proweld Performance. These bolts are reuseable and will not break as easily as the stockers. One hole looks like its buggerd up but it holds a bolt just fine. Feel free to ask any question.
