Thank you I would appreciate it, I have found all the parts I would need for the M12x1.75 I will hold off any ordering until I hear for sure from someone. I will be Going with Aeroquip as it does come with an Aluminum Cap to Protect the connection.Next time I change my oil (probably a month or so as I just changed it) I can get you the exact measurement if someone else hasn't gotten it by then and you still need it.
