Disc Brake swap-A body Rotors

I played with wheel adapters when I was a teenager, and after a few weeks of dealing with them, I took them off and threw them away. They rob you of an inch of clearance, and don't like to stay tight. There's nothing like driving down the road and having your wheels want to fall off.

The wheel studs on your axle are only 7/16" studs, and by adding the adapters and moving the wheels out farther, it really adds a lot of strain to them. I really don't recommend them. I'd save the $50 and save for the Moser or Yukons. Moser used to sell shortened C Body axles for not a ton of money. I'm not sure if they still do or not.

Cass can set you up with some axles, ready to go, if you'd like.

I don't know if you get down to Montana very often, but if you did, you could pick them up in person.
