Need a little help with collision

[pepperman35]

I modified one of the pieces to the Institute concourse but the collision no longer works for the new shape (extraneous collision elements left over towards the back of the object). I am hoping some kind soul with 3ds max and appropriate havok tools can redo the collision for me. File is attached if you have some spare cycles.

I've changed the collision for you.

Thank you kind sir! Very much appreciated.
