i recently stripped either my drain plug or the thread inside of the oil pan. i wanted to try a new plug before i buy a pan, my plug is 17mm with 14mm thread. how come when i try to buy a new bolt only m13 and m14s show up?? do they not make any 17mm drain bolts? thats the only one that fits the oil pan. if anyone could share a link or help me out anyway it would be appreciated.
