As I said in the other post, I am about 90 % sure ( I have seen pictures......) that you will have have a new tunnel cover ( to replace the factory tunnel) . The tunnel cover will run from the firewall joint to just in front of the seat and the new tunnel cover will have to be as wide as the existing tunnel “ but 2 inches taller” someone who knows how to do sheet metal work will have to make you one.. unless you can
That’s why I use Richmond 5 speeds that don’t require this major floor modification. Also your factory molded carpet( that fits factory floor pans) will not fit this new Tremec required tunnel cover.
