Cossie 4x4 discs and calipers will go straight on.
2wd 4 pots(cossie) will go on with a tiny amount of work, just need to tap out the lug holes on hub to take bolt for 4 pot calipers, holes are already correct size for tapping, then straight on, on some you need to grind away a minute amount of caliper where the spacer is between the two halves.
