Should also add I found a online magazine that has most of the NP T-cases. Exploded view and parts and list the two sets of needle bearings.
NP129 is on page 6 within the magazine not the PDF file. Its a good alternative Exploded view to the common one floating around.http://www.yumpu.com/en/document/view/47321199/transfer-case-parts-a-amp-reds/10
looks like the shorter needle bearings length is .120OD x .740 length
. The longer is .125OD x .935 length
If your looking at page 6 and the exploded view they are parts 99&101 (short) and 107&110 (longer).
There is also part "113", another set (15) of needle bearings. Those I'm sure are the obvious larger ones.
Think I might have answered my own question. BUT.... the AMC eagle bible says 85 needle bearings but the order catalog says you need 82. Ill have to count the old ones. Guessing if I put in 82 and there is still room Ill add more. What I dont get is that 85 is the addition of two sets close to each other with the same size. 41 and 41 makes sense 42.5 and 42.5 does not. no half bearings.
