Dan, a 6 pound lead hammer is a must. You can toss the plastic sand filled one. Many sources but here is my favorite:
Cobra Valley's Muther Thumper Lead Hammer Spinner Removal Tool
This is the one I have now but it is pretty beat up:
American Hammer 6 lb. Lead Hammer
Use anti-seize when you put them back on.
You will thank me.
