Anyone know the thread size of the diff drain plug??
 

I have searched and came up with nothing. If anyone knows the size and pitch, that would be great if you let me know. Need to know asap

If you have the bolt you can take it in to lowes and they have threaded holes they can test it on to find out.

i'll do that if no one knows

Measured it and it is a m18 and the threads are 1.5 as it matchs up perfectly with the oil cooler threads. If someone can back me up on this that would be great.
