There are some threads or articles on the web but won't you also need new spindles and maybe hubs?

Easiest method would be to go find a 70's K-20 and pull the axle or just the knuckle (with all parts). For $100 or so you'll have plenty of donor parts. If you are adding a booster then you also need the appropriate brackets (donor truck) and possibly the rod that connects to the pedal. Also requires a proportioning valve (part just after the master cylinder) and a new master cylinder. Full axle swap is easy if the gears are the same. Once you have spindles off it's a good time for new wheel bearings, lockout hubs etc... it all adds up and I would have a backup plan for getting to work on monday morning.
