Boy, I thought a 231 in good shape would go quicker, anyone got an OBO? I'd be willing to go lower for a FR 4x4 member.

IIRC 1997 was a new spline count for input shaft, would have to be a 97 or later GC I believe. Read through this to get a good knowledge base for your project.

Im missing that balance looking thing on the shaft between the np231 and the yoke. is that thing important?

I'd assume so if the Jeep engineers incurred the cost, but can't say for certain.

Any idea if this is a bolt in for a 95 YJ with an automatic transmission?

the balencer is there for the short shaft TJs.
the grand has a longer wheel base thus angels creat less vibrations.

use the novak link to find the spline info.
as for the YJ if the spline count is right it should be a bolt in case.

Sounds like it's time to cut it up and build a box4rox

lol....not for me. I am looking into a HERO transfer case and will most likely use the black box from northwest fab whan the project gets moving.

look up the HERO cases, they make ATLAS look like a sami case. 40 spline shafts are standard in these things.
this last Hammers race had 20 Atls failures and zero HERO failures this says something for sure.....
I must say a 5k for a transfer case it better not fail!
