how feasable or is it even possible to have a small shaft machined to fit into an input shaft of a autotrac transfer case that you could bolt a yoke onto? Im doing a frame up build soon and want to do a my 6.0/t56/ divourced autotrac case to run the 6 speed and keep my 4 wheel drive. Any machinist out there? Cost isnt much of an issue, going to technical school and I could get the cnc class to machine me it if needed or possible

 

T56 and 4wd is not an option as far as I know!

 

It might be difficult to fit a divorced t-case & T56 in a RCSB. You might be able to get some sort of one-off shaft made, but it's still gonna take some ingenuity to make it all work.

Before you commit, I'd say start by taking measurements of all of the drivetrain components, estimate shaft lengths, and see if it is realistic to persue. A longer wheelbase would make it alot easier.

 

Thats why it will be a divorced transfer case set up, google image it, you'll see what Im looking at doing

Im done some quick measurements, Im pretty sure a t56 is slightly shorter then a 4l60e, and theres not much space required between the two to run a divorced setup, about 6 inches or so. That means the rear shaft will only have to be shortened about 6inches and the front shaft lengthed about 6, which isnt very much. It wont be operating at any extreme angles because the truck will be lowered with a c-notch, Im confident it can be done and still keep it as a daily driver without worry
