I can find the part number in a bit... I did find it, I think I have the part number in my build thread (URL in my signature). It is M22x1.5 and the part I found is a coupler from an industrial equipment. My plan is to cur off the one end. But it has the flair and the right thread pitch and count. You should be able to see in my build thread my mock up of the EGR pipe.
