amc th400 questions

[wheelinjp]

will a gm np203 bolt up to an amc th400 that came with quadratrac at the rear output? I am trying to build a doubler for an amc powered rig. It currently has a t-18 and dana 20. I was thinking of loping the pass front output off the dana 20 and just mounting an np 205 divorced behind it? But if I go auto what are my options for gear reduction or doublers?

Quadratracks have a unique (very long, course spline) output shaft. As far as I know, NO other transfer case will bolt to it.

However, I changed out the output shaft to a Chevy in my AMC TH400 and am running an Atlas right now. So by changing to a Chevy output, you should be able to run any Chevy t-case also.

And rebuilding a TH400 to replace the output isn't particularly hard.
