9.25 corporate trac-loc rear axle in 2001 1500 4x4. Rebuilt clutches, retaining bolt came out in two peices. Having no luck getting a replacement bolt. Dealer shows bolt ( except trac-loc). Standard is square shouldered, mine is tapered like a lugnut. The tip is also tapered and length different. Even tried trans shop that specializes in 4x4 repair. Everyone acts like they have never seen a bolt like this. Ordered one that looks right, but wrong size. Surely I dont have a one of a kind. If you have one, or know the part # I would appreciate any help.

 

No reason to post twice. Someone gave you a party number in your other thread

 

That is the bolt for open diff, mine is longer, thicker, tapered at the tip and under the head.

 

I would suggest either a junkyard or maybe calling a differential shop like Randy's ring and pinion

 

Thanks
