Does anyone know how strong the case of the small CIM is? I'm working on a drivetrain to play in an off-season, and I'm currently mounting the DeWalt/CIM combo using a pair of U-bolts. Look at the attached pic to see how this works. (Yes, the U-bolts are exactly the right size to hold the CIM.

) For various reasons, I would like to move one bolt further up the CIM case, probably 1/2 inch from the back. The CIM seems pretty solid, but I don't want to damage it. Is tightening the U-bolts likely to dent the case or otherwise cause problems?
Thanks!
