Ireppond,
There are two rubbers required to finish off the hole in the carper around the gear lever.
Nr 1 is about a 4 inch rubber ring which is sewn into the carpet. Note, if I am correct the lever is not exactly in the middle of the tunnel, it is slightly over to the left.
Nr2 is a rubber boot that fits over the gear lever and into the rubber ring discussed above.
Regards
Chris
