Recently had to replace a torn lower IMRC gasket on my 1998 Cobra, had a bit of a hard time finding the correct O-ring style gasket. Of course I didn't realize they were different until it was torn apart. The parts stores all list 96-98 as having the same gaskets but they are not. Though I'd throw this out there for anyone having trouble finding the o-ring lower IMRC gaskets.
