A good rule of thumb is to keep the pitman arm the same length as the high steer arm, [one to one ratio], however many trucks have a longer pitman arm that would make the wheels turn quicker.
I have not been a big fan of chevy tie rod ends because they use a smaller thread [7/8" compared to the larger 23x1.50] and the head of the end is also larger. The FJ80 ends are available right and lefthand thread and have proven very dependable.
We can supply our arms with the chevy taper.
The factory axles use a 8 7/8" ring and pinion [GM 12 bolt] that GM sold the rights to in 1956. You must upgrade the birfield joint to a aftermarket unit.
Your sucess will depend on how you drive your truck. If you are worried about breaking then I would advise Rockwell 2 1/2 ton axles. I have seen many Dana 60's and even Unimogs go south under heavy throttle.
