Got the Transmission in and it works great,I have received the bolts from the dealer to install the drive shaft section from the center bearing back,I did not remove the bolts and am not sure witch bolt goes were?  

There are 2 sets of 4 bolts,the set of darker bolts has a #6 on the head. The polished bolts have a #6 with a dot.  My question is were do the set of dark bolts with #6 go,Center carrier or rear diff flange?

Thanks for your time.

They are the same.

 

Superceded part #s would be my guess.

 

I've never differentiated between them but you could put the shiny ones at the diff maybe Zinc/galv coated more rust resistant?

Thanks,good point Gloyale. After a closer look the darker bolts are coated so i'm going to attache them at the diff. flange.
