I did a conversion and the only thing I had to do with the tunnel was to cut the opening in the floor a little bigger to fit the lower shifter boot.
Other that that you can't tell the difference.
i just checked to see if i have a air box silencer ... i guess i dont? theres a hole entering the fender ? plus i got a drop in K&N is there anyway kind of induction that would be more benefical then that ? even if it is 2 horsepower?
