When you first posted this question I had a look in the service manual and no such luck on the bolt specifications in the drivetrain section under rear suspension )I think thats the section, it was a few days ago now.
I wouldn't guess that I was the only one that did this for YOU. Having never had this bolt out of my sled before I didn't know its characteristics, and even if I had it out before, it would be easy enough to tell you the wrong info, and then you would have been in a worse predicament and would have cursed me for telling you the wrong info.
My point is, its possible that no one new the answer off the top of their head without going out and taking the bolt in question out of their sled.
I understand you are frustrated, but generalizing that this forum is a load of $#!T is not right, just look around at the boat loads of info. If you scroll through the pages of posts yes there are some that have ZERO replies or senseless replies but for the most part they are pretty valuable!
If you wanna see crap information with a bunch of kids bitching, or talking about their 20hp gain from a $#!Tload of sponsor stickers they got for free from the internet check out HCS under the phazer section!
