Any one have a part # for the adapter need for the awd 4l80 conversion? I've been searching but never found out exactly which one I need or where to get it from.

 

Are you talking about the adapter housing or the input gear for the transfer case? The adapter housing is just the regular 6 bolt 4x4 housing.

EAD Performance makes a resplined 32 spline input gear for the nvg149

the PN in there should work if the AWD input is the same as the 4x4.

gm PN 88962329

I bought my from gmpartsdirect, I would just google that PN and gowith the cheapest

And the adapter housing IS different from the 60e and 80e, something I learned the hard way.

 

Nah the nvg149 input is different



There is no stock replacement for it that is why you have to get the resplined one from EAD performance. It's a lot more expensive than the regular 4x4 input as well.

 

4x4 input for reference

 

thanks black04 yes its the input gear im looking for.

 

ya that is way different, weird, cause i think somebody in the thread called that a nvg149 input.

 

2nd that. I don't think EAD had a part # listed. Just call Justin @ EAD and tell him you have a NVG149 AWD transfer case. You will also need the trans to t-case adapter. IIRC, it was around $485 shipped with the $80 core charge for everything.

Here are a few more pictures from EAD of their crossmember adapter 9two reinforcement gussets not shown) and the input shaft. The crossmember adapter has held up really well and was about $35 shipped.
