I will start a small build thread once this gets moving a little more. I believe AXIS also has automatic adapters developed as well
Depending on cost vs cash I am also considering a complete suspension change, basically jettisoning anything hanging below the frame and upgrading, being a 117" wheel base leaves little option except custom. Reliability being the focus.
As most people who have built up an older rig know it is like setting up dominos, when the first one falls its is hard to stop until there all down.
I am staying with the NSG 370 trans, I have purchased a "new" one for the price you stated, hopefully it won't be a problem but it does have a warranty. Plus I replaced flywheel & clutch so everything is new forward of the XTR. AX15 will not interface with my transfer case. I am sure you reviewed the NOVAK site for pros and cons on the various transmission choices.
