OK, so which gears do i need for my 04 10 bolt?
Motive G885430 or GM10-430?
Best i can tell the difference on G885430 is the pinion in this gear set will accept the factory ABS reluctor. Soo is that what i need?

 

I don't think so. An 04 truck would not have an ABS ring on the pinion.

 

That very well could be... I have no clue. I've never messed with suspension or rear ends in my life.... BUT that is about to change.....
