Yah, I've been wondering about this too. Had some oil leaking from my snout, assuming the seal is bad. Sounds like from what i've seen you can cut that bottom bolt with a dremel (or something else) and then replace it with an m8 x 50mm, 1.25 pitch stud and then just use a nut over the top of that. I've also seen people mention hitting that tube/ nipple with a mallet until it is pushed down far enough for the bolt to clear. But honestly I'd like to hear input form others who have experience with this.
