Bignscar My 51 6400 has that same 2-speed axle works fine !
That's good to hear, I'd really like to keep the rear axle.
What's your power train set-up?
My goal is to be able to drive it a lot
Have a smooth ride on the freeway
Pull a 5th wheel camper
Add 4wd
Possibly go big block, like 427 or 454 eventually
I have a 5.3 4wd powertrain I can use now though
Brought it home today.
