anyone happen to know this? i bought a clutch line from msa thinking it was to replace the dampener but doesnt so i need to find an adapter to do so. i have no measuring tools available to me right now so someone plz help me out. i am thinking it is 3/8 npt but am unsure without something to measure with. -edit- should be the same as 280zx brake lines etc really prob the same as all nissan brake line sizes.
