The new axel is wider than original and will use metric brake line fittings and wheel studs. I had to remove and replace spring perches and shock mounts on the axle tube. I used aftermarket E-brake cables.

I'm hoping not to have to do anything that drastic, but thanks for the info.

Because disc brakes are easier to work with. They are also more efficient.
