If you are using all Strange stuff, you can provide your wheel to wheel dimension and pinion offset, and they can figure it from there. They can figure axle stick out for the brake kit you are using. And give you cut lengths. Use your pinion CL tool, do the math to verify.

Wheel face from pinion CL - housing end - axle stickout - minus brake hat thickness = cut length.

Strange makes good stuff. No reason to use the Wilwood/Aerospace stuff if you are using their axles and ends. And getting everything from them eliminates stuff not fitting.
