Hello

I am wanting to convert my car from 4spd to 5spd, using a type 9 box from a sierra, what i would like to know is ;

1, do i have to cut the tunnel for the gearstick
2, can i use the existing flywheel and clutch
3, do i need to remove the welded mounts from the tunnel for the 4spd box.

if anyone can help i would be most grateful.

cheers
Jeremy
