Can anyone confirm for definite that the top fitting on a sport Oil drain is 3/4 jic? (I have done the older style drain mod on a non sport head and fitted the 90 elbow into the head but need to confirm pipe fitting size from standard sport pipe so I can buy the correct 3/8 to ?? jic adaptor nipple). Picture borrowed from another post.
