To determine exactly which hubs you need you'll need to find your bearing numbers. Most likely you have # 25580 and # 14125A but verify to be sure.

If these are correct you'll next want to find the diameter of your wheel studs and if you have E-Z Lube axles.

If the studs are 9/16 inch use # AKHD-865-7-1-EZ-K for E-Z Lube axles and # AKHD-865-7-1-K for standard axles.

For 1/2 inch studs instead use # AKHD-865-7-2-EZ-K for E-Z Lube or # AKHD-865-7-2-K for standard axles.

Then you need 12 inch brake assemblies. For a self-adjusting kit use # AKEBRK-7-SA. Both sides are included and labeled to make installation easier. They only need to be adjusted once when install them. You'll likely need the Mounting Bolts and Hardware # BRKH12 as well.
