Dana 20 "T-shift" Twin Stick help....

What position does rear selector need to be in to engage front high or 4wd high?

Background:
In the process of converting my Dana 20 t-shift X-case to twin shick (stage 1 -no internal mods/not removing retainer pins yet... ie there exists what I call "Stage 2")

My understanding is that "stage 1" benefits of twin sticking are:

easier t-case operation than single lever shifting
and
2wd (rear only) Low

I have disconnected the front and rear shift rails from one another and can get RWD high, RWD low, and 4wd Low... but can't get the Front rail to pull away from case to engage 4wd high????



Thanks,
Chad

Got it resolved.

FYI:
The detent springs are different lengths for front or rear selection rail... if they get swapped you get the above described problems with shifting/selection.
