Try going from the top with 3/8" drive socket and ratchet and pipe .... thats all i used. You could easily do this repair in a parking lot its soo easy. Its kinda shooting blind, but if you know where it is the job is much easier. Make sure to use antiseize on those threads! Also, if you run the car for a lil while to heat up the manifolds, it makes removal easier. But be very careful! Hot parts burn skin fast.
