Rearend question for a 65 Cuda

As far as stock axles go with the small bolt pattern, the 8.75" is your srongest choice. You could pretty easily have a Dana 60 made to that length with that bolt pattern, but it wouldn't be cheap.

This guy could set you up, and he isn't outside of driving distance for you to pick it up. SHipping on an axle can be hundreds of dollars. I'm not even sure what it would take to ship one across the border.
