This seal is confirmed to work on: CB, CD, BB5, BB6.  May fit other platforms.
 
All stainless nuts and bolts allow this gasket to be swapped between cable sets, unlike the OEM gaskets.  The plate is made out of extremely stiff and high temperature resistant carbon fiber embedded PET plastic.  This material starts to weaken around 400F and melts at 480F, significantly higher than the rubber in the OEM gasket.  The seal itself is 3D printed 95A polyurethane which comes standard in black, red, and fuscia.  The cable support bracket bushing comes in the matching color and is the exact dimensons of the OEM bushing, but removable!
 
The CB has stick on spring nuts and you must loosen the seal from the chassis from under the heat shield which is a PITA!  Removing cables in the future is easier as you can remove those nuts and install the studs through the OEM holes from inside the cabin.  Non marring spring flanged lock nuts prevent anything from rattling loose.
