My 2 bits, do not alter anything! Just get a case of beer and do some exact comparisons or measurements . Take your time, this stuff is too expensive to start altering things. This is not a Chevy where you have to shim or alter stuff. Mopar does not historically have an issue in this area? Get the bellhousing stamp number and do some research on applications?? Just a thought , might get you know where but at least eliminate that. Good luck.
