Hello all,

Potential dumb question alert.

While at the junkyard scoring fenders for my square body there was an HD2500 next to me. The rear axle was 70 removed and just waiting for me to take it home.

It has disk brakes and I glanced under it assuming it was a 14 bolt. Did this year come with the 10.5" 14 bolt or the 11.5 AAM??

After some research I am getting all different answers of what year the 11.5 began in the 2500 trucks. Rock auto list a multitude of covers and gaskets (9.5-11.5) so that is no help. Some internet info say it changed in 2001, some say it did not?????

Trying to save a trip back if it is the 11.5. That is overkill for my suburban.

Thanks,
Chris
