Just wondering if anybody knows the length & thread pitch of the pinion shaft lock bolt... if I ever dig up a posi to replace the blown gov-lock in my 3.73 disc axle, I think I want a new bolt in there. (Had too many of those suckers snap on me already, I want to be prepared!) Or is this a dealer-only bolt (special threads or design, etc)?

Thanks!
