Oh ok. I think the axle housings themselves should be the same. So basically you need to pull axles, then pull the whole knuckle off of each side. But if it was me I'd just pull the entire axle assembly and take it home with me. it can't possibly be that expensive. A whole disk brake dana 44 front axle should be like $150.

You don't necessaryily need a different booster. Most likely your master cylinder has a bore size that is not suitable for the disk brake calipers, so you'll need on of those. You also need a disk brake specific combination valve or at least a new pressure reducing valve for the rears. The rest is lines and hoses.
