Re: 14 bolt question

I always find this confusing. IIRC, American Axle always built the 14 bolt. They were spun off as a separate company in the early 1990's. Dodge trucks started using american Axle 14 bolts in 2003. Prior they were using Dana's in the HD trucks.

But the GM guys don't call the 14 bolt a AAM until it went to a 11.5" gear. <shrug>
